Filter by:Newly released guidelines recommend increased physical activity (PA) and reduced sedentary behaviors (SB) to improve glycemia and prevent the onset and progression of type 2 diabetes (T2D). Typically, 30-60 min bouts of PA are advocated per day. Although this approach increases PA, it does not decrease the length of the sedentary periods through the day. This is important because recent epidemiological data suggest that frequently interrupting sedentary time improves glucose control even in people who achieve the recommended levels of PA. Preliminary experimental data suggest that breaking up prolonged sedentary time by performing multiple short bouts (5 min) of PA throughout the day, may improve glycemia more than performing a single continuous bout of PA, and thereby potentially be a novel strategy to prevent T2D. The improvement in glycemia was observed even when the total amount of PA and total energy expenditure were matched, suggesting that how and when PA is performed over the day may matter more than how much PA is done. However, important gaps in knowledge remain including: (1) whether similar benefits on glucose control would be observed in adults with prediabetes, a clinically relevant population that is at high risk of developing T2D; (2) whether these effects are sustained or diluted over time, and (3) what are the mechanistic underpinnings. To address these gaps, the investigators propose to measure the acute and chronic effects of PA breaks on glucose control and the underlying mechanisms in individuals at risk of developing T2D. Sedentary men and women with prediabetes (n=66, 50% F) will be randomized to either an intervention designed to interrupt SB with 5-min bouts of brisk walking performed hourly for 9 hours/day, 5 days/week (BREAK) or a control condition consisting of 45-min of brisk walking performed as a single daily continuous bout, 5 days/week (ONE). The two 3-months interventions will be matched for total active time.
Background: Previous epidemiological and animal studies have suggested a strong relationship between prediabetes and Alzheimer's disease. Recently, we demonstrated that plasma β-amyloid (Aβ), a potential biomarker for Alzheimer's disease, was elevated in individuals with type 2 diabetes. However, few studies have investigated the associations of plasma Aβ40 and Aβ42 concentrations with prediabetes. Objective: we aimed to investigate the associations of plasma Aβ40 and Aβ42 concentrations with risk of prediabetes in two independent studies. Design: We performed a case-control study and a nested case-control study within a prospective cohort study. In the case-control study, we included 571 newly diagnosed individuals with prediabetes and 571 control participants. Prediabetes individuals were consecutively recruited from subjects who attended the outpatient clinics of Department of Endocrinology at Tongji Medical College Hospital from 2012 to 2015. Concomitantly, we recruited healthy controls from a general population undergoing a routine health checkup in the same hospital. One healthy control was selected at random for each prediabetes individuals according to age (±3 years) and sex. The inclusion criteria of participants were as follows: age ≥30 and ≤80 years, BMI <40 kg/m2, no history of prediabetes and diabetes mellitus, no history of receiving pharmacological treatment for hyperlipidemia, nor any clinically systemic disease, any acute illness, and chronic inflammatory or any infective disease. An independent nested case-control study was conducted within an ongoing cohort study, namely the Tongji-Ezhou cohort. Briefly, 5533 participants, including 3101 retired employees and 2432 working employees, were enrolled from Echeng Stell and received healthcare for a baseline investigation between 2013 and 2015. The first follow-up for all participants was finished by mid-2020. Considering the low incidence of prediabetes among young working employees, we performed the nested case-control study among retired employees. During the follow-up, 119 new-onset prediabetes cases were diagnosed within the retired employees according to fasting plasma glucose. We randomly selected the control participants who matched 2:1 to the cases by age (±3 years) and sex from the retired employees with normal fasting plasma glucose. The inclusion criteria were the same as the case-control study; 2 new-onset prediabetes cases aged >80 years were excluded. Additionally, 17 cases without enough plasma were excluded. Finally, 100 individuals with new-onset prediabetes and 200 well-matched control participants were included for the analysis of the nested case-control study. These two studies were approved by the Ethics and Human Subject Committee of Tongji Medical College. All enrolled participants in the two studies were of Chinese Han ethnicity and provided informed written consent. Plasma Aβ40 and Aβ42 concentrations were simultaneously measured by validated assay platforms from Meso Scale Discovery (MSD; Rockville, MD, USA).
This trial studies the effect of exercise and nicotinamide riboside on muscle health and insulin resistance in adult survivors of childhood cancer with prediabetes (elevated blood sugar level that is not high enough to be considered diabetes). Nicotinamide riboside is a dietary supplement which is similar to vitamin B3. Information collected in this study may help the future development of regimens to improve metabolic outcomes such as muscle health and insulin resistance (when the body is not normally responding to insulin) in childhood cancer survivors.
Our hypothesis is that switching from the current standard of care twice daily Adoport (Tacrolimus) to once daily Envarsus (tacrolimus) in patients who have impaired glucose tolerance post-transplant will lead to an improvement in their glucose tolerance, and may reduce the subsequent incidence of PTDM.
Gestational diabetes is one of the most common medical disorders in pregnancy and is a major risk factor for the postpartum development of dysglycemia. Despite the high risk of developing dysglycemia, 50-80% of women with gestational diabetes are not receiving testing within a year postpartum. The investigators will conduct a prospective cohort study to examine the use of continuous glucose monitoring immediately postpartum to estimate the risk of maternal dysglycemia postpartum.
In this project, the investigators will perform a multicenter randomised controlled trial to determine whether advice to consume a moderate, whole food-based low-carbohydrate high-fat (LCHF) ad libitum diet (CarbCount program) can produce and maintain equal remission rates of type 2 diabetes (T2D) as a nutritionally complete very-low-calorie formula diet followed by a energy-restrictive (i.e., calorie counting) diet (DiRECT principles). Within the principles of each approach, the dietary goals and change will be adjusted according to individual needs/capabilities conducive to long-term adherence. Furthermore, the investigators aim to determine whether the rate of diet-induced remission is reflected in/can be predicted by baseline or diet-induced changes in glucose variability (e.g., time-in-range measured by continuous glucose monitoring) and other factors such as anthropometric changes and genetic susceptibility. Each center will also conduct locally-lead standalone mechanistic research, including analyses of intra-abdominal/hepatic fat accumulation, adipose tissue biopsies and/or measurements of energy metabolism. Additionally, changes in medication use, nutritional status, cardiovascular disease risk, as well as adverse events, will be monitored.
The microbiota is associated with a wide spectrum of diseases including diabetes and non-alcoholic fatty liver disease. In this study we will investigate if the bacteria F. prausnitzii, which is a part of the human gut microbiota, can improve metabolic parameters in subjects with impaired glucose control.
The purpose of the study is to learn about how type of exercise influences measures of appetite regulation.
This study is a prospective cross-sectional study. The investigators enroll participants form the department of endocrinology and of metabolism, China Medical University Hospital. In total, 400 participants , composed of 100 of type 2 diabetes , 100 of pre-DM and 200 healthy participants. The investigators apply tongue diagnosis system, pulse wave analysis, body constitution questionnaires, and nailfold capillaroscopy to assess the differences of TCM diagnosis. After collecting the tongue coating and analyzing the metabolite signals with a flying mass spectrometer, The investigators collect the data to establish metabolite pattern and biomarkers. This study aims to identify the clinical symptoms of DM with TCM diagnostic tools and investigate the pattern difference and treatment for DM. Furtherly, the investigators add mass spectrometer to analyze the metabolites of tongue coating, the investigators propose to establish a metabolite pattern and biomarker to identify important biological indicators of DM.
Participants who were previously Viome costumers who signed informed consent to participate and self reported type 2 diabetes or pre-diabetes were enrolled. They provided stool samples to VIOME and were provided with precision diet and supplement recommendations. The information obtained from this study is used to train a model to predict diabetes and/or risks of developing diabetes.
