Physical Activity Drop-out Ratio in Patients Living With Type 2 Diabetes
Diabetes MellitusType 23 morePhysical activity (PA) - understood as any bodily movement produced by skeletal muscular that requires energy expenditure, related to leisure time, for transport to get to and from places, or part of a person's work - is a powerful force for good regarding type 2 diabetes mellitus (T2DM). However, fewer T2DM patients sustain the lifestyle recommendations suggested by health care professionals (HCP): 40% of patients did not follow-up on general medical recommendations regarding lifestyle changes. Using a socio-ecological approach - that aims to deal with the different levels of PA influences - may be a good solution to integrate the behaviour change techniques in health care professionals' consultations to prescribe PA efficiently. The investigators' protocol has two aims. The primary aim is to evaluate the effectiveness of theory-driven PA intervention based on SEM among people living with T2DM. A secondary aim is to explore the feasibility and perceptions/experiences on the PA adherence process in T2DM patients while using the socio-ecological approach and to understand the HCP's viewpoint in its applicability in the Spanish Healthcare system. The investigators want to know the how, not the what, related to PA prescription.
Weight Loss Clinical Decision Support
Diabetes MellitusType 21 moreDespite steady increases in obesity prevalence, the more than 12 million obese U.S. adults with type 2 diabetes (T2DM) and severe obesity encounter a number of barriers to adopting effective surgical and pharmaceutical treatments, including: (a) both patients and primary care clinicians frequently underestimate the effectiveness and potential benefits of obesity treatments; and (b) both patients and clinicians typically lack access to evidence-based estimates of the patient-specific potential benefits and risks of appropriate obesity treatment options. This project addresses these important obstacles to evidence-based obesity care by providing accurate, patient-specific estimates of benefits and risks of various obesity treatment options to inform shared decision making about obesity treatment. In this project the study team will implement a scalable, web-based point-of-care decision-support intervention in primary care that provides patient-specific estimates of obesity treatment benefits and risks in a randomized trial in 40 primary care clinics with 15,810 eligible patients, and assess intervention impact on (i) appropriate active management of obesity in eligible patients, (ii) weight trajectories, and (iii) patient and clinician satisfaction with the decision support intervention.
Home Food Delivery for Diabetes Management in Patients of Rural Clinics
Diabetes MellitusType 22 moreOur long-term goal is to transform rural residents' management of T2DM. This study's objective is to determine the effectiveness of an intervention that is scalable and sustainable and promotes patient adherence by mitigating rural food insecure participants' difficulties associated with completing existing interventions. Our specific aims are: Compare the effectiveness of the Healthy Food Delivery Intervention (HFDI) plus standard care and standard care alone to improve diabetes-related outcomes among rural food insecure patients with T2DM. Hypothesis: Compared with standard care alone, patients receiving the HFDI plus standard care will demonstrate improved: H1 glycemic control as measured by HbA1c; H2 cardio-metabolic risk factors: blood pressure, fasting glucose, fasting lipids, and BMI; H3 self-management: self-efficacy, adherence to self-management behaviors, and medication adherence; H4 patient-centered outcomes: diabetes-related distress, diabetes-related quality of life, and diabetes-related complications. Compare the effectiveness of the HFDI plus standard care and standard care alone to improve diet quality among rural food insecure patients with T2DM. Hypothesis: Compared with standard care alone, patients receiving the HFDI plus standard care will demonstrate improved: H1 Healthy Eating Index 2015 (HEI-2015) scores; H2 fruit and vegetable consumption. Compare cost-effectiveness to understand HFDI plus standard care costs in relationship to outcomes in relation to standard care alone. Hypothesis: The HFDI will be cost-effective based on traditional cost per additional quality-adjusted life year gained.
Decreasing Cardiovascular Risk for Patients With Diabetes
Diabetes MellitusType 2Cardiovascular disease (CVD) complications are the leading cause of diabetes mellitus (DM)-related morbidity and mortality, creating a significant burden on the public health system. This burden is, in part, attributable to poor medication adherence, with 21-42% of patients failing to properly adhere to their care. Importantly, this issue is especially pronounced in minority and low-income populations, which show higher rates of chronic illness and lower medication adherence. Interventions that foster and reinforce patient-centered communication between clinicians and patients show promise in improving health outcomes. However, they have not been widely implemented, in part due to a lack of compelling evidence for their effectiveness in primary care settings. Project Objective: The investigators propose to evaluate the impact of a patient activation program: Office Guidelines Applied to Practice (Office-GAP) combined with mobile text messaging reinforcement (Way to Health [W2H]) on medication adherence in patients with DM compared to mobile texting alone. Office-GAP incorporates shared decision-making and a decision/support checklist to be completed during office visits, to foster patients' investment in their own care. W2H is a texting service that informs and encourages patients to adhere to goals and improve communication. The long-term goal is to develop a model that can reliably improve and sustain adherence and can be successfully implemented in primary care clinics to close the morbidity and mortality gap for minority/low-income DM patients. The hypothesis is that the combined face-to-face patient activation and texting- delivered reinforcement methods will facilitate communication between patients and providers, improving the frequency, accuracy, and timeliness of communication while reinforcing shared goals and engendering mutual respect more than texting alone. Improved communication between patients and providers may improve medication adherence, blood sugar, cholesterol, blood pressure control, and patient satisfaction with providers, and ultimately decrease burden of illness. Research Strategy: The investigators will conduct a randomized community-based clinical trial in Federally-Qualified Health Centers (FQHCs) in Michigan enrolling 378 patients in 17 teams. All patients will receive usual care and medication for DM and CVD prevention. Eight teams will use W2H alone, and 9 teams will combine Office-GAP with WTH. The investigators will evaluate the impact of shared decision-making strategies for patients and providers. Impact: If successfully translated to clinical practice, these interventions have the potential to significantly impact patient care in FQHCs, improving outcomes for DM and CVD. This research also paves the way for shifting clinical practice across a spectrum of chronic disease where medication non-adherence is an issue.
Pathobiology of Remission of Type 2 Diabetes
Newly Diagnosed Type 2 DiabetesObeseWe propose to investigate effects of HP and HC weight loss diets in Newly Diagnosed T2DM (NT2DM) women and men for 6 months for remission of Type 2 Diabetes. Our long term goal is to establish a weight loss diet plan for remission of NT2DM which would be adaptable for use in physicians' clinics and metabolomics predictors for assessment of remission. The overall objective of this study is to determine if remission of NT2DM can be induced by dietary manipulation using a HP diet and the pathobiology of this remission. We hypothesize that NT2DM subjects will have remission to NGT on the HP diet when they are provided the food and daily menus for compliance. The rationale is the HP diet is palatable for subjects to continue after the 6 month study and stay in remission using diet plans we provide. We will compare the effects of the HP vs HC diet on remission. Specific aims of this study are to determine the effects of the HP and HC diets on NT2DM obese subjects in a 6 month feeding study and determine: (a)remission of NT2DM to Normal Glucose Tolerance(NGT), (b)weight loss, (c)improvements in metabolic markers, Cardiovascular Risk Factors(CVR), and inflammation markers, and epigenetic DNA methylation changes and pathways involved with remission and metabolomic markers to establish predictive markers of remission of NT2DM. We propose to use a non-pharmaceutical means (HP diet) for remission of T2DM and weight loss and determine the pathobiology involved in improvement in metabolic and CVRs by interrogating the samples with emerging technologies. The proposed research is significant because if we can demonstrate the HP diet cause remission of NT2DM to NGT along with other metabolic improvements, it would be a significant improvement in health risk and medical cost to subjects.
Raclopride-PET/MRT
Diabetes MellitusType 2Cerebral insulin resistance plays an important role in the development of obesity and diabetes mellitus type 2. The aim of this project is to examine the effect of human nasal insulin on the dopaminergic system. Therefore, characteristics of cerebral dopamine receptors before and after administration of nasal insulin vs. placebo shall be analyzed in a randomized way. Moreover, the investigators plan to examine the insulin action on cortical and subcortical activation in humans and the interaction of dopamine metabolism with [11C]-Raclopride-PET/MRI. By performing fMRI measurements, insulin sensitivity of the central nervous system can be investigated simultaneously. Recruiting is planed as a two-step process.First 12 normal-weight (BMI 20-25 kg/m²) men should be examined. If first results show a insulin-dependent effect on the availability of dopamine receptors in the human brain, recruitment of 12 overweight men will get started.
Effect of Probiotic Supplementation on Endothelial Function II
Cardiovascular DiseaseDiabetes Mellitus1 moreResearchers at MCW have discovered a new pathway that links the type of bacteria present in the intestines to the severity of heart attacks. This discovery of a relationship between intestinal bacteria, bacterial metabolites, and severity of heart attacks means that for the first time, the investigators may be able to determine a person's probability of having a heart attack via non-conventional risk factors. This may provide opportunities for novel diagnostic tests as well as a potential for therapeutic intervention. The link between gut microbiota and the severity of heart attacks may also lead to novel therapeutic approaches (probiotics, non-absorbable antibiotics) to prevent heart attacks from happening. The studies proposed will test the hypothesis that altered intestinal microbiota are mechanistically linked to the pathogenesis of cardiovascular disease. The investigator's objective is to determine whether inflammatory markers in the blood are decreased and endothelial cell function improved by a probiotic in patients with established coronary artery disease. Furthermore, the investigators wish to elucidate a mechanism by which the gut microbiota regulates serum inflammatory markers. Specific Aim 1 will determine the impact of a probiotic on circulating leptin and TMAO levels, conventional risk factors for cardiovascular disease and diabetes (total cholesterol, LDL cholesterol, oxidized LDL, triglycerides, C-reactive protein, serum amyloid A, fibrinogen and adiponectin, glucose-dependent- insulinotropic polypeptide (GIP), glucagon-like-peptide (GLP-1), glucagon, insulin), and their relationship to the intestinal microbiota (15 representative microbial groups) as non conventional risk factors. Several blood samples will be collected to measure biomarkers. Participants will provide periodic stool samples in order to measure gut bacterial biodiversity. Lastly, endothelial cell function (flow mediated dilation) will be measured in order to assess blood vessel function. Specific Aim 2 will determine the impact of a probiotic on metabolites derived from the intestinal microbiota as candidates for non-conventional risk factors of cardiovascular disease. The relationship between metabolites derived from the intestinal microbiota, endothelial cell function and risk factors for cardiovascular disease identified in Specific Aim 1 will be correlated.
Regulation of Endogenous Glucose Production by Central KATP Channels
Type 2 Diabetes MellitusGlucose Metabolism Disorders2 moreType 2 diabetes affects the ability of the body to process glucose (sugar). Under fasting conditions, the liver is able to make sugar to maintain glucose levels in an important process called endogenous glucose production (EGP). Previous studies suggest that the central nervous system (CNS), including the brain, helps to regulate levels of glucose in the body by communicating with the liver. This process can be impaired in people with type 2 diabetes, and can contribute to the high level of glucose seen in these individuals. The purpose of this study is to understand how activating control centers of the brain with a medication called diazoxide can affect how much glucose (sugar) is made by the liver. This is particularly important for people with diabetes who have very high production of glucose, which in turn can lead to diabetes complications.
