Pathogenesis of Kidney Disease in Type 1 Diabetes: a Modern Kidney Biopsy Cohort (The PANDA Study)...
Type 1 DiabetesDiabetic Kidney Disease3 moreDiabetic kidney disease (DKD) occurs in up to 40% of people with type 1 diabetes (T1D), often leading to kidney failure and markedly magnifying risks of cardiovascular disease and premature death. Landmark T1D kidney biopsy studies identified the classic pathological lesions of DKD, which have been attributed largely to hyperglycemia. Recent advances in continuous glucose monitoring (CGM) and automated insulin delivery have facilitated improved glycemic control, but the residual risk of DKD continues to be high. In addition, obesity and insulin resistance (IR) have accompanied intensive glycemic therapy and may promote mitochondrial dysfunction and inflammation. Deciphering the molecular underpinnings of DKD in modern-day T1D and identifying modifiable risk factors could lead to more effective and targeted therapies to prevent DKD.
Diet in Elderly With Type 2 Diabetes
SarcopeniaSarcopenic Obesity4 moreSarcopenia is characterized by progressive and generalized loss of skeletal muscle mass which may affect performance. Diabetes can affect muscle cell function, making sarcopenia worse. This is a prospective and interventional study on a elderly population affected by type 2 diabetes mellitus. All subjects, recruited will undergo tests for the diagnosis of sarcopenia according to the EWGSOP2 criteria. All subjects, both sarcopenic and non-sarcopenic, will be introduced to a targeted nutritional program aimed at improving the composition of the diet, in terms of both micro- and macro-nutrients.
Evaluation of Diabetic Retinopathy Using Ultra-Widefield Fundus Images Compared With Two-Field Fundus...
Retinal DiseasesDiabetic Retinopathy3 moreThis study aims to compare the accuracy of evaluating diabetic retinopathy using ultra-widefield fundus images versus two-field fundus images. The hypothesis is that screening and grading diabetic retinopathy based on ultra-widefield fundus images may yield higher accuracy compared to the use of two-field fundus images.
Retinal Microvasculature by Optical Coherence Tomography Angiography During Integrating Physical...
Diabetes ComplicationsDiabetic retinopathy is a common condition of diabetes and can lead to blindness, making it one of the most feared complications of diabetes. Recently, it has been proven that the parameters measured by Optical Coherence Tomography (OCT) Angiography: the vascular density of the macular retinal capillary plexi and the foveolar avascular zone, can be modified after a high-intensity sports training program in healthy subjects. the team wants to study the evolution of the macular, in type 2 diabetic subjects, before and after a stay in a care structure dedicated to the multidisciplinary and integrative management (nutrition, physical activity, therapeutic education) of a duration of 3 weeks.
3D Foot Scanner Reliability for Footwear Fit and Design
Diabetes ComplicationsThe investigators will carry out a proof-of-concept study in 20 adult healthy male and female volunteers in order to: assess a 3D foot scanner's reliability. Specifically, the investigators will assess its variability during repeated foot scans of the same subject's foot. Three repeated foot scans will be carried out by two different examiners to measure intrarater and interrater reliability (Intraclass Correlation Coefficient
To Study the EGG Abnormalities in Healthy Subjects and in Patients With Idiopathic and Diabetic...
GastroparesisDiabetes Complications2 moreElectrogastrogram (EGG) is a non-invasive method for recording myoelectric activities by placing electrodes on the abdomen surface. Many studies suggested EGG measures the gastric slow wave frequency effectively; the relative change in EGG signal amplitude would reflect the contractility of the stomach. Thus, this technique is used to study the pathophysiological processes of diseases such as functional dyspepsia and many more . The present study aims to study the EGG pattern in healthy individuals in Indian population and the factors associated with it.
The Effect of Roxadustat on Renal Oxygenation in Diabetes Nephropathy
Diabetes ComplicationsDiabetes; Nephropathy (Manifestation)The study will investigate if treatment with Roxadustat improves kidney oxygenation in diabetic patients with nephropathy receiving treatment for renal anemia, compared to patients receiving treatment with darbepoetin alpha. Participants will be randomized to either treatment, and receive equal care for renal anemia. Kidney oxygenation will be examined before treatment start and after 24 weeks using BOLD-MRI (blood oxygen level-defendant MRI), a non-invasive method available for measurement of tissue oxygenation levels that is comparable with direct invasive measurement of partial oxygen pressure. Blood and urin samples will be collected in connection to these visits. The primary endpoint is the change in medullary and cortical R2* (inversely proportional to the tissue oxygenation content) after 24 weeks. Secondary endpoints will be albuminuria and urinary levels of ROS (evaluated by electron paramagnetic resonance (EPR) spectroscopy with CPH spin probes).
Peer Support for Patients With Diabetic Foot Ulcers
Diabetic Foot UlcerDiabetic Wound5 moreThe objective of the study is to develop a peer support program that helps improve ulcer care in patients with a diabetic foot ulcer (DFU).Diabetes, peripheral arterial disease (PAD), foot ulceration, and subsequent amputation are unevenly patterned in terms of racial/ethnicity, socioeconomic status, health insurance, and geographic area. The project will identify opportunities to reduce health disparities among economically marginalized patients regarding DFU outcomes.
Neuromuscular Electrical Stimulation For The Treatment of Diabetic Neuropathy
Diabetic Peripheral NeuropathyDiabetic Neuropathies2 moreDiabetic neuropathy (DN) is the most common complication of diabetes, affecting almost 50% of people with diabetes over the course of their lives. Symptoms vary from numbness to burning, aching and hypersensitivity in the lower limbs, indicative of sensory nerve loss. Motor neurons can also be affected, leading to muscle weakness and mobility issues, thus preventing patients from engaging in daily routines. Further sequelae include foot ulceration and Charcot neuroarthropathy, which are risk factors for lower limb amputation and mortality. In the United Kingdom, the annual costs of DN alone exceed £300 million, with further complications expected to cost an additional £1 billion. Currently, management strategies for DN focus on prevention and pain management. Neuromuscular electrical stimulation (NMES) is a novel nonpharmacological intervention for people with DN. NMES is the application of electrical impulses which are of sufficiency intensity to improve artificial contraction of the muscle tissue and may help with DN by improving nerve conductivity through direct stimulation of the nerves.
Quantifying Artificial Pancreas-related Changes in Diabetic Neuropathy
Diabetes ComplicationsDiabetes Mellitus2 moreA complication of diabetes mellitus is damage to nerves called neuropathy. There are several mechanisms involved that will lead to the development of neuropathy. Neuropathy can lead to foot ulcers, infections and amputations. Patients with neuropathy may also experience pain, which can be difficult to control and the medications are limited by side effects. Despite this there are no approved treatments to reverse the progression of neuropathy and the management of patients is focused on controlling blood glucose and other metabolic factors to prevent neuropathy and its symptoms from getting worse. Patients with type 1 diabetes are prescribed multiple daily injections (MDI) of insulin to manage their glucose control. However, insulin pump therapy and, more recently, automated insulin delivery (AID) or the Artificial Pancreas can be used as the insulin delivery method for patients with type 1 diabetes mellitus. Manchester Diabetes Centre is the first adult diabetes centre in Europe to pioneer and use a commercially-approved AID in clinical practice. Insulin pump therapy and AID have the advantage of being able to provide insulin at variable doses, which is closer to the natural process occurring within an individual without diabetes. Both are currently considered to be the most physiological method of insulin delivery and have been shown to improve glycaemic control, quality of life (QOL) and reduce the risk of hypoglycaemia (low blood glucose level). The investigators have previously shown in a small group of people that use of an insulin pump therapy may improve symptoms of painful neuropathy via a more stable glucose profile. The peaks and drops in insulin may make neuropathy worse. In this study the investigators aim to investigate the use of insulin pump therapy and AID in their effect on neuropathy. This will be in comparison to a control group of patients on MDI. The investigatorsbwill use a variety of neuropathy measures and symptom questionnaires to assess structural and functional neuropathy status. The investigators hypothesise that those patients receiving the newer technologies will demonstrate an improvement in symptoms and nerve regeneration. This finding would have a significant impact for patients as it would provide evidence to suggest that those patients with neuropathy should be put onto an insulin pump or AID to improve neuropathy and its symptoms. As these are treatments that are already available on the NHS to patients satisfying specific criteria this study aims to show benefit in this cohort of patients which can be implemented immediately in clinical practice.
