Impact of Metabolic Surgery on Pancreatic, Renal and Cardiovascular Health in Youth With Type 2...
Type 2 Diabetes MellitusObesity11 moreType 2 diabetes (T2D) in youth is increasing in prevalence in parallel with the obesity epidemic. In the US, almost half of patients with renal failure have DKD, and ≥80% have T2D. Compared to adult-onset T2D, youth with T2D have a more aggressive phenotype with greater insulin resistance (IR), more rapid β-cell decline and higher prevalence of diabetic kidney disease (DKD), arguing for separate and dedicated studies in youth-onset T2D. Early DKD is characterized by changes in intrarenal hemodynamic function, including increased renal plasma flow (RPF) and glomerular pressure with resultant hyperfiltration, is common in Y-T2D, and predicts progressive DKD. Studies evaluating the two currently approved medications for treating T2D in youth (metformin and insulin) have shown these medications are not able to improve β-cell function over time in the youth. However, recent evidence suggests that bariatric surgery in adults is associated with improvements in diabetes outcomes, and even T2D remission in many patients. Limited data in youth also supports the benefits of bariatric surgery, regarding weight loss, glycemic control in T2D, and cardio-renal health. While weight loss is important, the acute effect of bariatric surgery on factors such as insulin resistance likely includes weight loss-independent mechanisms. A better understanding of the effects of bariatric surgery on pancreatic function, intrarenal hemodynamics, renal O2 and cardiovascular function is critical to help define mechanisms of surgical benefits, to help identify potential novel future non-surgical approaches to prevent pancreatic failure, DKD and cardiovascular disease. The investigators' overarching hypotheses are that: 1) Y-T2D is associated with IR, pancreatic dysfunction, intrarenal hemodynamic dysfunction, elevated renal O2 consumption and cardiovascular dysfunction which improve with bariatric surgery, 2) The early effect of bariatric surgery on intrarenal hemodynamics is mediated by improvement in IR and weight loss. To address these hypotheses, the investigators will measure GFR, RPF, glomerular pressure and renal O2, in addition to aortic stiffness, β-cell function and insulin sensitivity in youth ages 12-21 with T2D (n=30) before and after vertical sleeve gastrectomy (VSG). To further investigate the mechanisms of renal damage in youth with T2D, two optional procedures are included in the study prior to vertical sleeve gastrectomy: 1) kidney biopsy procedure and 2) induction of induced pluripotent stem cells (iPSCs) to assess morphometrics and genetic expression of renal tissue.
Myocardial Function and Vitamin D Supplementation in Diabetes.
Diabetes ComplicationsVitamin D Deficiency2 moreVitamin D deficiency is recognized as a cardiovascular risk factor. Diabetic patients are of major risk for cardiovascular diseases and typically present with Vitamin D deficiencies. Myocardial function is altered in both type I and II diabetic patients but no data is today available on the effect of Vitamin D supplementation. The aim of the study will be to investigate myocardial function (by deformation imaging techniques) at rest and during low-dose dobutamine stress echocardiography in both type I and II diabetic patients. Within each diabetic population, myocardial function will be compared at baseline between the vitamin D deficient and non-deficient individuals. Furthermore, the investigators will study the effect of a 3 month supplementation in those with deficiencies.
Effect of Automated Insulin Delivery on Early-stage Diabetic Complications
Type 1 DiabetesAim of this study is to verify the effects of an advanced HCL (Medtronic Minimed™ 780G) compared to SAP with PLGS on metabolic outcomes and markers of early microvascular damage in a population of adults with T1D previously treated with CSII. Evaluation of endothelial disfunction and autonomic neuropathy will also be performed.

Concordance in Diagnosis of Periodontitis in Diabetic Patients Between an Indirect Method Based...
Diabetes ComplicationsPeriodontal DiseasesPeriodontitis, a known complication of diabetes, is an infectious disease that destroys bone and gums. Studies have shown that diabetes favors periodontitis, and that periodontitis contributes to its aggravation. The positive impact of treating periodontitis on the cost of diabetes care has been demonstrated and the French national health system fully covers the treatment of periodontitis for diabetic patients. Unfortunately, 80% of diabetic patients do not visit their dentist enough. Although diabetologists regularly see their patients and are aware of the importance of treating periodontitis,they do not have the expertise to diagnose the condition whereas a specialist dentist can often diagnose it just by looking. This study aims to develop a solution combining the dentist's expertise with that of the diabetologist. This would be based on analysis of a photograph of the patient's oral cavity, taken in the department. So far, no studies have ever evaluated the performance of an expert dentist for diagnosing periodontitis from a simple photograph made by non-dental experts in a diabetic department. The hypothesis is that the concordance in the diagnosis of periodontitis between an indirect method based on a photograph of the oral cavity and a direct method based on clinical examination of this oral cavity (reference) in the diabetic patient would be satisfactory.
Reducing Disparities in the Quality of Advance Care Planning for Older Adults
Metastatic CancerCongestive Heart Failure7 moreThis study compares the effectiveness of two different approaches to advance care planning among older African Americans and older Whites living in the community. The two approaches are a structured approach with an advance care planning conversation led by a trained person using Respecting Choices (First Steps) and a patient-driven approach which includes a Five Wishes advance care planning form written in plain language. The study will determine which approach is more effective at increasing advance care planning within each racial group and reducing differences between the two groups in advance care planning.
