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.
Cystic fibrosis is a genetic disorder caused by mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene, leading to pulmonary infections, sinus disease, pancreatic insufficiency, hepatobiliary disease and male infertility, with respiratory failure being the primary cause of death. Cystic Fibrosis Related Diabetes (CFRD) in one of the most common complication of cystic fibrosis (CF) and it's associated with a worse respiratory and nutritional state, with a negative impact on life expectancy. It differs from type 1 diabetes and type 2 diabetes for particular characteristics making this disease a separated clinical entity. To date, there is a lack of evidence on many aspects concerning this disease: - the pathophysiology of the disease: decreased insulin secretion has historically been seen has the major trigger for CFRD, but data about this mechanism are scarce and conflicting. Moreover, the role of insulin-resistance seems to be not consistent, but pulmonary exacerbations are very common and, in this setting, insulin sensitivity can worsen significantly. - the relationship between its development and particular genetic settings: certain CFTR genotypes are known to be most related to the risk of diabetes, and only few susceptibility genes for type 2 diabetes have been evaluated as potential predisposing factors for CFRD. - the relationship between the therapeutic optimization and its impact on metabolic status and lung function: CFRD is known to be associated with worse clinical outcomes, reflected in more frequent clinical exacerbations, greater reduction in lung function, poorer nutritional status and decreased survival. It has also been demonstrated that insulin therapy can improve pulmonary function, increase body weight and reduce lung exacerbations. However, no study on the clinical impact of the optimization of insulin therapy on pulmonary outcomes and life expectancy are available in this population. - finally, no data about potential predisposing pre-transplant risk factors for development of post-transplant DM are available For this reason, the investigators have structured a study with the aim to: - characterize the pathophysiological process leading to CFRD, with assessment of the relative contribution of the insulin resistance and the β-cellular secretion impairment - define the prevalence of CFRD in relation to the mutations of the CFTR gene and to the presence of candidate genes for the development of type 2 diabetes - perform a proteomic analysis to identify potential proteomic biomarkers among CFRD patients - evaluate the body composition, muscle performance and respiratory outcomes in patients on insulin therapy, before and after therapeutic optimization, in a follow-up period of 24 months. - identify eventual predisposing factors for the development of post-transplant diabetes in subjects without pre-transplant CFRD.
Therapeutic effectiveness of coldness in relieving pain and reducing inflammation has been known for many years now. Over that time, various coldness therapies have gained in popularity, including winter swimming, snow baths or whole body cryostimulation (WBC) . Recent researches have shown positive effects of WBC on metabolic profile, low-to-moderate chronic inflammation and related diseases (e.g., obesity). WBC could be, thus, intended as an adjuvant method in the treatment of dysmetabolic conditions, such as overweight or obesity. WBC is a cheap easily accessible practice, with a few well-defined contraindications and limited non severe possible adverse events, if performed in specialized centres. At the same time, in sport science appears data, which indicated on inhibition of adaptive changes induced by regular training. The primary aim is to define, through a randomized controlled approach, the relative effectiveness of up to 20 consecutive sessions of either WBC, high-intensity intermittent training (HIIT), or their combination (WBC and HIIT) in improving the metabolic status of overweight and obese subjects. The effects will be assessed, at different time-points, in terms of insulin sensitivity and modification in the profile of hormones regulating the energy metabolism (adipokines, myokines, bone-derived hormones) and the inter-organ cross-talk.
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.
