Grain Fibre and Gut Health
Intestinal DisorderGlucose Metabolism Disorders1 moreWholegrain fibre is known to affect on the gut health, but also may cause intestinal discomfort. Thus, many individuals may avoid the consumption of whole grain cereals in spite of their known health benefits, and may in this regard consume more restricted diets. In the preset study the aim was to technologically modify the cereal fibres to improve its usability and to maintain its health beneficial properties. The objective was to investigate intestinal fermentation of grain dietary fibre and associated effects on gut-mediated metabolic health, such as immunological health and adipose tissue function. The hypothesis was that whole grain products maintain their original beneficial health effects and may be better tolerable when the bran is technologically modified. Additionally, it was hypothesized that gut-mediated bioavailability of plant cell wall compounds and their metabolites affect the metabolic health through their immunomodulatory effects.
Inhibition of the Endogenous GIP Response With a GIP Receptor Antagonist
Glucose Metabolism DisordersDelinieation of GIP's effects during an oral glucose tolerance test (OGTT) in humans using GIP receptor antagonisation.
Physiology of GIP(1-30)NH2 in Humans
Glucose Metabolism DisordersGlucose-dependent insulinotropic polypeptide (GIP) is a gut-derived incretin hormone that affects glucose, lipid and bone metabolism. Secretion of GIP into the blood stream from enteroendocrine cells is stimulated bu nutrients in the gut lumen and results in potentiation of glucose stimulated insulin secretion from the pancreas. The objective of this study is to investigate the physiology of GIP(1-30)NH2 in humans with insulin secretion as the primary endpoint. Furthermore the effects on on plasma/serum levels of glucagon, C-peptide, glucose, bone markers (CTX and P1NP) will be measured.
Effect of "Nicotinamide Mononucleotide" (NMN) on Cardiometabolic Function
Glucose Metabolism DisordersThe purpose of the study is to understand the effect of the dietary supplement "Nicotinamide mononucleotide" on metabolic health in people.
The "Metabolically-obese Normal-weight" Phenotype and Its Reversal by Calorie Restriction
Glucose Metabolism DisordersObesity3 moreThe prevalence of overweight and obesity in Singapore is approximately half of that in the United States, yet the incidence of type 2 diabetes is similar, and is expected to double in the near future. This indicates that metabolic dysfunction, particularly insulin resistance, is widely prevalent even among individuals who are considered normal-weight or lean by conventional measures, i.e. body mass index (BMI) and percent body fat. These individuals are often referred to as "metabolically-obese normal-weight" (MONW), and have increased risk for cardiometabolic disease despite their normal BMI and total body fat values. The prevalence of the MONW phenotype varies across populations and differs markedly among different ethnicities. However, our understanding of the complex interactions between ethnicity, body composition, and metabolic dysfunction and its reversal remains rudimentary. Previous attempts to characterize the MONW phenotype are confounded by the small but significant differences in BMI or percent body fat between groups (even if all subjects were lean, within the "normal" range), with MONW subjects being always "fatter" than the corresponding control subjects. There are no published studies that prospectively recruited groups of metabolically healthy and unhealthy lean individuals matched on BMI and percent body fat. Furthermore, although weight loss improves body composition and many of the cardiometabolic abnormalities in most obese patients, little is known about the possible therapeutic effects of calorie restriction in MONW subjects. Accordingly, a better understanding of the MONW phenotype and the evaluation of therapeutic approaches for its reversal will have important implications for public health. By facilitating earlier identification of these subjects, who are more likely to go undiagnosed and thus less likely to be treated before clinically overt cardiometabolic disease develops, results from this study will allow for earlier and effective intervention.

Diabetes MellitusDiabetes Mellitus2 moreThe purpose of this study is to characterize the safety, tolerability, pharmacokinetics (PK) and preliminary food effect of PF-04991532 following single escalating oral doses in healthy adult subjects.
Effect of Location of Feeding on Glycemic Control in Critically Ill Patients (ELF)
Glucose Metabolism DisordersCritical IllnessThe purpose of this study is to investigate the effect of location of feeding on glycemic control in critically ill patients. The investigators hypothesize that glycemic control in critically ill patients who receive enteral nutrition through postpyloric location (beyond stomach) will have better glycemic control compared to critically ill patients fed gastrically.

Diabetes MellitusDiabetes Mellitus4 moreTo compare the effects of different initial insulin dose regimens during the short-term insulin intensive treatment on time to glycemic goal, hypoglycemia prevalence, glycemic variability and other safety problems in newly diagnosed type 2 diabetes mellitus(T2DM) patients, in order to investigate the rational of formula based initiation regimen.
