NASH and Type 2 Diabetes: Role of the Receptor Activator of Nuclear Factor-κB (RANK) and Its Ligand...
Diabetes type2NASH - Nonalcoholic Steatohepatitis1 moreNon-alcoholic fatty liver diseases (NAFLD) include several entities ranging from simple steatosis to hepatic fibrosis or cirrhosis. Steatosis, considered benign and the first stage of the disease, is characterized by the accumulation of triglycerides in the liver. It may in some cases progress to nonalcoholic steatohepatitis (NASH), which is characterized by the presence of a marked inflammation with or without fibrosis. NAFLD is the most common liver disease in the world and is particularly associated with type 2 diabetes (T2D) (80% in the diabetic population). While NASH is characterized by a higher prevalence of mortality from a cardiac and hepatic (cirrhosis and cancer) origin, therapeutic resources are almost non-existent. RANK (receptor activator of NF-kB) and its ligand RANKL (a member of the TNFalpha family) have emerged in recent years as new players in bone pathophysiology. By binding to its receptor, RANKL induces a number of signaling pathway and in particular the NF-kB pathway (Nuclear factor-kB), a major player in inflammation. Recent literature shows that the role of RANK / RANKL is not confined to the bone but may be involved in the genesis of inflammation in other tissues. It has been shown recently that a high circulating level of RANKL was a risk factor predictor of T2DM. Furthermore, the invalidation of RANK specifically in hepatocytes protects from insulin resistance and hepatic steatosis induced by a high fat diet in mice. The aim of our project is to provide a proof of concept that the RANKL / RANK system plays an important role in the pathogenesis of NAFLD and in the progression of this disease to NASH. The aim of our project is to provide a proof of concept that the RANKL / RANK system plays an important role in the pathogenesis of NAFLD and in the progression of this disease to NASH. The investigator propose to study the RANKL / RANK expression in serum and liver biopsies of type 2 diabetic patients at different stages of NAFLD.
The Effect of Shear- Force at the Skin in Patients With Diabetes Mellitus
Pressure UlcerDiabetes Mellitus Type 21 moreThe objective of this study is to acquire knowledge about the development of reactive hyperaemia and inflammatory responses of the skin after shear- force and pressure loading. We want to investigate if patients with diabetes type 2 will develop more skin damage, because of a decreased microvascular function. The second objective of this study is: to investigate if the cytokine production of the skin is increased in patients with type 2 diabetes with a history of Charcot osteoarthropathy in comparison with patients with neuropathy without a history of Charcot osteoarthropathy. The participant is asked to put his left arm on a support cushion. Then we mark an area of 2.5 cm x 3 cm with a permanent marker at the plantar aspect of the left fore-arm and the adhesive side of a Sebutape is placed within this area for collection of IL-1α/ total protein concentrations in a non- loaded situation (event 1) for two minutes. Second, we measure the cutaneous blood cell flux within the borders of the marked area with a Laser doppler. Finally, we measure the erythema index in this area with a colorimeter. Then we place the shear- pad over the marked area we apply 9,8 Newton (N) pressure with 19 N shear- force for half an hour. After this period a new Sebutape is placed for two minutes, followed by cutaneous blood cell flux and the erythema index measurement within the borders of the marked area. We repeat these measures after 15 minutes, 30 minutes, 45 minutes and 60 minutes, At the same time we performed the same experiment at the right arm, but instead of loading this arm with shear- force and pressure, we apply only 9,8 N pressure at this arm. The same measures with the sebutape, laser doppler and colorimeter are done before and after loading of the skin. The measures are repeated at 15 minutes, 30 minutes, 45 minutes and 60 minutes.
Meta-analyses of Impotrant Food Sources of Sugars and Incident Cardiometabolic Diseases
Diabetes MellitusType 25 moreThere is an urgent need for stronger evidence to support recommendations for the role of sugars in diabetes and related cardiometabolic diseases. Although large prospective cohort studies have shown a significant positive association of fructose-containing sugars-sweetened beverages with incident obesity, diabetes, heart disease, and stroke, these associations do not appear to hold true for total fructose-containing sugars and other important sources of free fructose-containing sugars such as pure fruit juice, yogurt, or even cakes and sweets. As dietary guidelines have moved away from macronutrient centric recommendations towards more food and dietary-pattern based recommendations, this inconsistency in the data has not been appreciated. There remains a focus on free sugars, in the absence of sufficient information on the role of different food sources of fructose-containing sugars in diabetes and related cardiometabolic diseases. A systematic review and meta-analysis of prospective cohort studies is considered to be the "Gold Standard" of evidence. To provide evidence-based guidance to support the development of public health policy in relation sugars and the primary prevention of diabetes, we will conduct a series of systematic reviews and meta-analyses of the relation of food sources of fructose-containing sugars with incident type 2 diabetes and related cardiometabolic diseases in prospective cohort studies.

Measuring the Preferences of Patients With Type II Diabetes Using Best-worst Scaling and Discrete...
Type II DiabetesIn 2012, the FDA Center for Devices and Radiological Health (CDRH) issued guidance to clarify the principal benefit-risk factors FDA considers during the reviews for premarket approval applications and de novo classification requests. In addition to a detailed description of benefits and risks, CDRH listed "patient tolerance for risk and perspective on benefit" as a factor that CDRH may consider in regulatory reviews. It underlined the need for developing methods to measure patient preference and incorporate it into regulatory decision-making. The purpose of this study is to advance methods for patient and community engagement in patient-centered outcome research (PCOR) and has three objectives. First, demonstrate good practices for patient and community involvement in PCOR projects by applying principles of community-based participatory research (CBPR). Second, address methodological gaps pertaining to the use of stated-preference methods in studying preferences in PCOR. These include identifying the best methods for designing a preference study and strategies for analyzing variation in preferences. The investigators also seek to assess the relevance of stated-preference methods to patients and stakeholders using both qualitative and quantitative methods. Third, demonstrate good practices for applying stated-preference methods by studying the preferences of patients with type II diabetes. While type II diabetes provides an important case study, this research will advance approaches and methods that will be broadly generalizable to other diseases, and to diverse patient and stakeholder groups. Clinical Significance: This project will illustrate and advance methods for assessing the values of patients and stakeholders. It will demonstrate how CBPR methods apply to PCOR studies and the value of stated-preference methods in measuring the preferences of patients and stakeholders and directing health care.
