Healthy Liver - Healthy Brain
Metabolic SyndromeNon-Alcoholic Fatty Liver Disease2 morePeople with liver disease report difficulties with attention and problem-solving skills. Diet plays an important role in the development of liver disease and/or pre-diabetes. The purpose of this study is to examine whether participation in a brief diet intervention (up to 3 weeks) can improve brain and liver health and function.
Personalised Medicine in Pre-diabetes and Early Type 2 Diabetes
Pre DiabetesType 2 Diabetes MellitusPrediabetes is a common condition in overweight individuals affecting approximately 35% of American adults and 30% of Australian adults. Like diabetes, prediabetes is a serious risk factor for cardiovascular disease, eye, kidney and liver disease, and some types of cancer. Appropriate blood glucose control is crucial in preventing pre-diabetes complications and onset of diabetes, yet clinical practice, backed by randomised trials, reports that many patients treated with standard dietary guidelines or with the first-line treatment of diabetes patients, metformin, do not improve blood glucose control sufficiently. The overarching goal of the present project is to improve the efficacy of metformin mono-therapy in pre-diabetes and early type 2 diabetes.
Wake Forest Alzheimer's Disease Clinical Core
Alzheimer's DiseaseMild Cognitive Impairment1 moreEfforts to find treatments for AD have yielded only modest benefits, likely because longstanding AD pathological processes induce irreversible neurological compromise. These processes begin years before the onset of clinical symptoms. This possibility has been incorporated into a model describing stages of AD development, articulated by the NIA/Alzheimer's Association preclinical workgroup of which the Co-Director of the Kulynych Alzheimer's Research Center, Dr. Suzanne Craft, was a member. According to this model, the best hope for countermanding the effects of AD lies in intervening at the earliest possible point in the pathological cascade. There are several important ongoing efforts in adults with preclinical AD that directly target amyloid aggregation. Although this strategy addresses an important aspect of the AD pathological cascade, we believe that addressing metabolic dysfunction affecting glucose and insulin regulation offers a complementary approach, in that it may reduce amyloid burden and toxicity, while also directly enhancing synaptic health, brain metabolism, tau regulation and neurovascular function. The purpose of the ADCC is to identify and characterize early risk factors that predict cognitive decline and dementia in asymptomatic adults and adults with early signs of cognitive impairment. The data obtained from this study, collected at enrollment and follow-up will allow us to examine disease trajectory in individuals with and without prediabetes and other measures of glucoregulatory dysfunction in this process. The enrollees, who will be well-characterized with regard to cognitive and metabolic status through ADCC assessments, will provide an important resource for other local (institution) and national investigations. Data collected from participants enrolled in the ADCC will be stored indefinitely for future investigations.
To Identify Anytime Hyperglycaemia in Subjects With Normoglycaemia and Prediabetes
HealthyTo test these hypotheses, The Investigators will recruit 100 overweight and obese adolescents with HbA1c ranging across the ADA classification spectrum from normal to prediabetes,(nearly 40:normoglycemi, 30: IFG, 30:1GT) measure free-living glucose by continuous glucose monitoring (CGM), and assess the relationships among CGM outcomes, HbA1c, and OGTT results (FPG and 2-h glucose). Individual with overt diabetes will be excluded. This will be a 2 visit study. Subjects will be coming to Fortis CDOC after a minimum 8-hour overnight fast. Informed written consent and validated questionnaire in a language known to them (English/Hindi) will be obtained from all participants. Clinical details will be obtained from the case records of the patients. Note of visible markers of insulin resistance (acanthosis nigricans, buffalo hump, double chin, subcutaneous fat pads, skin) Anthropometry, skinfolds & blood pressure will be recorded. Overweight and, obesity will be defined according to predefined guidelines for Asian Indian. Abdominal obesity is defined as waist circumference of ≥ 90 centimetres (cms) in males and ≥ 80 cms in females. A blinded iPro Continuous Glucose Monitor (Medtronic MiniMed, Inc) will be inserted. After a calibration period of 1 hour, fasting laboratory result will be collected: FPG, HbA1c. HbA1c will be done by HPLC (NGSP approved, turbid inhibition immunoassay). Then subjects will consume 1.75 g/kg glucose, maximum 75 g (glucose beverage) and will have a second venepuncture 2 hours later for plasma glucose measurement. While awaiting the 2-hour venepuncture, participants will be provided instructions on CGM device care and calibration. Participants will be instructed to wear the CGM device for a minimum of 72 hours and to not change any of their current dietary or activity habits for the period of CGM wear. They will be trained to use a glucose monitor and collect capillary blood glucose values at least three times daily, prior to meals. Participants will also be asked to complete a simple log of their activity, as well as record dietary intake, and sleep and wake times. The iPro and log-sheet will be returned in person after a minimum of 72 hours of recording time. Investigators and patients will be kept blinded to CGM recordings throughout the study. Daily glycaemic variability will be assessed by the change in the mean amplitude of glucose excursions (MAGE) index, and through the standard deviation (SD) of the mean 24-hour blood glucose concentration. Day-to-day variability will be assessed through the mean of daily differences (MoDD in mg/dL). Daily glycaemic control will be assessed by the mean (M) daily CGM value, as well as by the times (in minutes/day) spent in optimal glycaemic range (70-140 mg/dL) and above predefined hyperglycaemic thresholds (140 ,180 and 200 mg/dL) together with the corresponding area under the curve (AUC) values. In addition, areas under 24-hour glycaemic traces (AUCs) will be analysed to estimate: overall hyperglycaemia (defined asAUC≥100 mg/dL over the full 24-hour period = AUCtotal);postprandial hyperglycaemia (AUC[0-4 h], i.e. for four-hour periods after each of the main meals and, if considered relevant by the core laboratory, after additional snacks = AUCpp); and basal hyperglycaemia, i.e. overall hyperglycaemia - postprandial hyperglycaemia (AUCb)
Models of Nutrition From Continuous Glucose Monitors
Diabetes MellitusType 24 moreWith this study, researchers want to conduct ambulatory studies in which people (healthy, with T2D, or at-risk of T2D) will consume a variety of pre-set and conventional meals in free-living conditions while wearing one or more continuous glucose monitors (CGMs) and, to assess physical activity, a smart watch. With data from these devices, researchers will develop algorithms that can predict the content of a meal.

A Virtual Cardiometabolic Health Program for African Immigrants: The Afro-DPP Program
Diabetes MellitusDiabetes Mellitus9 moreA pilot study titled "A Virtual Cardiometabolic Health Program for African Immigrants (The Afro-DPP Program) will be conducted to address the cardiometabolic of community-dwelling African immigrants who have multiple cardiometabolic risk factors including hypertension, Type 2 Diabetes, high cholesterol, and overweight/obesity. The proposed study will recruit a total of 60 participants and will use a non-equivalent control group design to test the effectiveness of the intervention at two African churches in the Baltimore, Washington, D.C. area. The two churches will be randomly assigned to the intervention or delayed intervention group. At the end of a 6-month follow-up period, the control church will receive the intervention (delayed control group). All participants will receive a Bluetooth-enabled digital scale (Omron Model: BCM-500) that measures body composition including Body Weight, Body Fat percentage, Visceral Fat, Skeletal Muscle percentage, Resting Metabolism and Body Mass Index. A Bluetooth-enabled blood pressure monitor (Omron Model: BP7250) will also be distributed to all participants. All participants will download the Omron Connect app which will allow the participants to sync participants' blood pressure readings and body composition readings into the app. The research team will access these readings to monitor study outcomes and participants progress during the follow-up period.
Testing the Effectiveness of Different Messaging Approaches to Increase Doctor Visits Amongst Individuals...
Type 2 DiabetesPre-diabetesThe purpose of the research is to test the effectiveness of different messaging approaches to nudge members of Vitality and Discovery Health, with risk factors for diabetes (based on data from the Vitality Health Check and Vitality Age assessment), to visit a doctor and test for diabetes. The messages are based on concepts from behavioural economics that aim to make information on screening more salient by using the concept of social proof (person like you) and an authoritative source (a diabetes specialist and the Vitality doctor).
