Filter by:Patients with type 2 diabetes have an increased risk of developing vascular complications. Microvascular dysfunction might be caused by the increased production of methylglyoxal under hyperglycaemic conditions. Methylglyoxal is a by-product of glycolysis and forms advanced glycation endproducts (AGEs) on proteins and DNA, thereby disrupting their function. Preventing methylglyoxal accumulation and AGEs formation may offer a therapeutic option for treating microvascular complications in diabetics. Pyridoxamine is a vitamin B6 vitamer that scavenges methylglyoxal and thereby inhibits the formation of AGEs. In this study, the researchers investigate whether pyridoxamine supplementation in type 2 diabetes improves microvascular function in the eye, kidney and skin, and reduces markers of endothelial dysfunction and glycation.
The goal of this, Retrospective and Prospective Low- Interventional study, is to implement health education interventions to promote self-care and reduce disease complications in DM Type 2 patients at higher risk of development/progression of Diabetic Retinopathy. ]. The main question it aims to answer are: - To evaluate the impact of a health education intervention on mental health, self-care behaviors, and disease knowledge in patients with Diabetes Mellitus Type 2 with high risk of development/progression of Diabetic Retinopathy. - To evaluate the impact of a health education intervention on the metabolic control of patients with Diabetes Mellitus Type 2 with high risk of development/progression of Diabetic Retinopathy. Patients will have to (V1 and V4): - answer three questionnaires, (Summary of Diabetes Self-Care Activities - SDSCA, QCD- Diabetes Knowledge Questionnaire and Depression Anxiety and Stress Scale" (DASS-21). - measurement of weight and height, to calculate BMI. - collection of glycated hemoglobin analysis (if they have been done in the last 3 months).
The goal of this observational study is to analyse and compare Diabetic Retinopathy severity level using 30º ETDRS 7-fields and Wide-field Imaging techniques using Clarus 500 (Carl Zeiss Meditech Inc., Dublin, USA) and Optos (Optos, Dunfermline, UK) in diabetic patients with mild to moderate diabetic retinopathy. The main questions it aims to answer are: 1. To compare the Clarus 500TM wide-field imaging technique with the ETDRS 7-fields method in the assessment of DR severity level using the ETDRS DRSS.2. To compare the two wide-field imaging techniques (Clarus 500TM vs OptosTM) in the assessment of DR severity level using the ETDRS DRSS.3. To evaluate the peripheral area imaged by the wide-field Clarus 500TM and OptosTM to characterize DR lesions distribution (predominantly observed within or outside the ETDRS 7-fields) and severity (according to the ETDRS standard photos).4. To determine the relevance and frequency of DR PPL, located outside the ETDRS 7-fields area, and to explore PPL occurrence in different DR severity levels. Participants will undergo a non-invasive ophthalmological examination, which includes BCVA, 7-fields CFP and UWF FP to assess ETDRS DRSS level.
The complicated schedules for administering topical steroid eye drops combined with forgetfulness and physical difficulties instilling the drops may compromise compliance; which in turn could increase the risk for secondary complications such as PME post-cataract surgery, especially in a high-risk diabetic population. Dextenza, a sustained- release steroid insert, could help preclude adherence difficulties and provide better bioavailability, being as effective as, or more effective than steroid drops in preventing PME. The aim of this study is to assess the incidence of PME in diabetic patients undergoing cataract surgery when comparing the Dextenza insert to topical prednisolone acetate 1% drops.
Retinopathy may be associated with diastolic dysfunction and/or coronary flow reserve in the heart, and albuminuria in diabetic patients. The objective of this study is to examine the cross-sectional relationships of retinopathy with indices of left ventricular diastolic function, coronary flow reserve and urinary albumin excretion, among diabetic patients.
