Filter by:Chronic hepatitis C infection has been linked to insulin resistance, which is the essential component of metabolic syndrome and type 2 diabetes mellitus. Resistin; an adipokine, has been demonstrated to stimulate the secretion of several inflammatory factors known to play a role in the induction of insulin resistance. we investigated the changes in insulin resistance after hepatitis C clearance in the era of direct antivirals.
The aim of the present study is to evaluate the implication of adipokines, inflammation, insulin resistance and endothelial dysfunction in the pathogenesis of preeclampsia and in pregnancy related complications.
The study aims to identify if Kelulut Honey can be a potential alternative for the use of preoperative carboloading instead of the commercially available product, Carborie.
This pilot randomized controlled trial seeks: (1) to determine the preliminary efficacy of our modernized collaborative care intervention for depression in improving the diabetes risk markers of hemoglobin A1c and insulin resistance and (2) to explore whether somatic depressive symptoms - i.e., hyperphagia (increased appetite/weight) and/or hypersomnia (increased sleep) - moderate the effect of the eIMPACT-DM intervention on diabetes risk markers.
This study will investigate how maternal emotional state following a controlled stress exposure in pregnancy influences blood glucose and insulin levels after eating a standardized meal, and whether the effects of emotional state on blood glucose and insulin is different after eating a healthy meal (low GI) compared to a less healthy meal (high GI).
Efforts in curing and preventing obesity and type 2 diabetes (T2D) have been elusive thus far. One reason for that is the lack of understanding of the role of the brain in the development and treatment of the disease. In recent studies, the hypothalamus was identified as part of a brain network including higher cognitive regions that is particularly vulnerable to insulin resistance. Furthermore, the central insulin response in this network predicted food craving and hunger. In this project, transcranial direct current stimulation (tDCS) is implemented as a tool to stimulate brain networks. The investigators hypothesize that stimulating the hypothalamus-cognitive network will enhance insulin sensitivity and reduce food intake, food craving and hunger. Furthermore, the project will provide the unique opportunity to investigate novel mechanisms of insulin resistance in participants who have been extensively metabolically characterized.
The process of surgery is a controlled trauma to the body. Trauma induces changes in metabolic function that have evolved to help the body survive injury. The normal balance among use of sugar, fat, and protein for energy production is thought to change during trauma and surgery. This altered metabolic function may contribute to adverse outcomes from surgical procedures especially in the setting of patients with obesity or Type 2 Diabetes Mellitus. However, very little is known about the specific changes in metabolism that occur during surgical procedures. The main objective of this project is to describe the metabolic changes that occur during a typical surgical procedure in detail. In order to measure the alterations in the balanced use of sugar, fat, and protein during surgery we will collect blood samples from patients before, during, and after spinal surgical procedures. Subjects will be enrolled in the pre-operative hold area, give informed consent, and have a dedicated peripheral IV catheter placed. We will recruit patients who are normal weight without diabetes, obese without diabetes, and obese with diabetes. The first specific aim is to characterize the metabolic changes in sugar, fat, and protein balance during surgery in metabolically normal subjects. The second specific aim to examine if there are differences in these changes in subjects who are obese or have diabetes. The final specific aim is to measure the changes in metabolism at high resolution using a method called metabolomics, which is analogous to genome profiling. This method measures hundreds of compounds produced in different amounts as metabolic balance changes. The major impacts that may be derived from these data range from a more thorough understanding of metabolism under trauma to identification of new markers for risk stratification and intervention to improve clinical outcomes. These data will help build the foundation for new approaches to understanding the physiological and metabolic responses to stress and trauma.
The purpose of this study is to investigate the feasibility of conducting a multicomponent lifestyle intervention research study within the UAB Family Medicine Clinic at Highlands and to obtain preliminary data on the effectiveness of the adaptive treatment strategies being investigated to produce improvements in insulin resistance. This study is a Sequential Multiple Assignment Randomized Trial (SMART) with initial randomization groups of individualized nutrition counseling vs. individualized exercise counseling. Note that these initial nutrition or exercise interventions are NOT intended to produce significant weight loss. Participants that do not sufficiently improve their insulin resistance score after 8 weeks will be re-randomized to 2nd stage interventions of either receiving dietary counseling for weight loss or receiving a prescription for metformin. We will collect data on the effectiveness of the intervention to improve insulin resistance/metabolic health in the family medicine clinic as well as potential predictors or moderators of treatment success.
Obesity and especially type 2 diabetes (T2D) increases the risk of neurocognitive dysfunctions including adverse effects on brain structure and function. Recent evidence from clinical studies have shown that T2D almost doubles the risk for dementia. As the population gets older, age-related chronic diseases, as T2D, become more prevalent. Scientific evidence is emerging that there are several links between metabolic and neurocognitive functions. Impaired insulin action (i.e. insulin resistance), the main hallmark of T2D, has been suggested as a likely shared common pathophysiological mechanism. However, the neural processes that determine how insulin resistance is are connected to the onset and progression of T2D and dementia remain unclear. In this context, the overall aim is to study brain insulin resistance to disentangle age-related and obesity related brain insulin resistance in healthy normal and overweight/obese persons at the age of 20 to 70 years . To this end, the investigators will assess brain insulin action using intranasal insulin/placebo during functional Magnetic Resonance Imaging (fMRI). Additionally, structural changes and cognitive processes will be assessed as secondary variables.
The investigators aimed to investigate hepassocin levels in patients with polycystic ovary syndrome (PCOS). There are 3 groups aged between 18 and 35 years as non-obese healthy women, non-obese women with PCOS, and obese women (BMI>30) with PCOS.
