Cohort studies show an association between increased intake of insoluble (cereal) fiber and decreased risk for cardiovascular disease, type 2 diabetes (T2DM), non-alcoholic fatty liver disease (NAFLD), cancer, infectious and inflammatory disorders. Intervention studies, specifically addressing non-fermentable carbohydrates instead of their food sources (whole grain, pulses, legumes) are still sparse. Whole grain trials reported beneficial effects, but cannot pinpoint these benefits on fiber, as minerals, vitamins, grain protein and food matrix contribute to the metabolic results. The antidiabetic effectiveness of cereal fiber might be explained by a) an increased secretion of incretins and other glucose-induced gastrointestinal hormones, b) an alteration of the gut microbiome, or c) a fermentation to short-chain fatty acids. Fermentable fibers (most of which are soluble) show these mechanisms, but lack strong diabetes-protective associations in cohort studies. In recent supplementation trials, insoluble, mostly non-fermentable fibers improved insulin resistance, glycemia and inflammation in patients with metabolic syndrome or prediabetes. Between 2022-2024, we want to assess the effectiveness of insoluble, poorly fermentable cereal fiber in a shorter Intervention period in patients with high responsiveness (insulin-naïve overt type 2 diabetes mellitus with insulin resistance and NAFLD), using a fiber drinking supplement. Our triple-blinded RCT compares the metabolic effects and mechanistic outcomes of isocaloric treatments with 15 grams of oat-fiber supplement per day (vs. placebo) in 92 patients, covering an intervention period of 12 weeks.
The primary objective of this study is to test the effect of a diet and exercise program in older adults with insulin resistance and a motivation disorder known as apathy. The main questions the study aims to answer are: 1. Does the diet and exercise program improve insulin resistance and apathy? 2. Does the addition of soybean to the diet enhance the effect? Participants will be given all meals for 12 weeks and will exercise under supervision. They will undergo a test of insulin sensitivity and complete questionnaires. Researchers will compare the groups given: 1. A diet to moderate the blood glucose response that contains soybean; and 2. A diet to moderate the blood glucose response that does not contain soybean.
- Prevalence of smoking in men and women ages 15 and over who currently smoke any tobacco product on a daily or non-daily basis Egypt smoking rate for 2018 was 21.40%, a 0.1% increase from 2016. - According to WHO reports, smoking is currently responsible for six million premature deaths every year, of which 600 000 individuals die from the effects of second-hand smoke. - Egypt is one of the 21 countries and territories of the International Diabetes Federation Middle East and North Africa (MENA) region. 463 million people have diabetes in the world and 55 million people in the MENA Region; by 2045 this will rise to 108 million. - The most profound impact of smoking in diabetic patients is on insulin sensitivity, Cigarette smoking worsens insulin-resistance in patients with diabetes, as smoking decreases subcutaneous absorption of insulin, resulting in increased dosing requirements. When the action of insulin is impaired chronically in smokers, a dose response relationship can be seen between the number of cigarettes smoked and the degree of insulin resistance. Consequently, quitting smoking should improve glycemic control. - Therefore diabetic patients can get huge benefits from tobacco cessation as they give their bodies chance to decrease percentage of nicotine and increase percentage of insulin so decrease risk of getting atherosclerosis, so smoking cessation improve glycemic control and insulin sensitivity.
Exercise represents an important tool in the prevention and treatment of metabolic disorders associated with obesity and aging, such as type 2 diabetes and cardiovascular disease. Besides skeletal muscle and its myokinins, the metabolic effects of exercise also rely on the induction of favorable changes in adipose tissue function. For example, adipose tissue is a source of lipokinins from the family of palmitic acid esters of hydroxy fatty acids (PAHSA), which have anti-inflammatory and insulin-sensitizing properties. We have recently shown that 4 months of exercise training increases PAHSA levels in adipose tissue and circulation. However, the mechanisms involved in the induction of PAHSA levels in response to exercise are unknown. The aim of the Effect of Acute Bout of Exercise on Levels of PAHSA (ETAPA) project is therefore to investigate the regulation of PAHSA metabolism in response to both acute and chronic exercise. To achieve this goal, we will employ state-of-the-art analytical methods to measure PAHSA levels in both adipose tissue and circulation of subjects of various ages and adiposity status. The main output of the ETAPA project will be the proof of principle regarding the important role of PAHSA lipokinins in exercise-induced enhancement of insulin sensitivity and the identification of potential drug targets that could be used to further improve PAHSA metabolism for the treatment of metabolic disorders associated with aging or obesity.
This study will examine if brain insulin resistance is a feature of depression in humans using magnetic resonance imaging (MRI) measures sensitive to brain insulin action. This study will examine adolescents, as depression onset commonly occurs during this age, and the impacts of cumulative medication exposure and other lifestyle-related confounds are also lower in this age group, improving our ability to understand the underlying biology.
This is a prospective observational study with a primary goal of monitoring changes in circulating bile acid profiles and parameters of glucose and lipid metabolism prior, during, and after cancer treatment with agents that directly impair insulin action: PI3K inhibitors, AKT inhibitors, and mTOR inhibitors. Patients will not receive any cancer treatment specifically for the purposes of this study. Rather, this study will be based on treatment decisions made independently by participants' oncologists according to standard of care or other clinical trial protocol. This study seeks to enroll at least 25 participants each for PI3K inhibitors, mTOR inhibitors and, once available for open-label treatment, AKT inhibitors.
The purpose of this study is to understand and determine whether Palmitoleic acid (POA), monounsaturated omega-7 fatty acid (exists in regular diet), improves insulin sensitivity and decreases liver fat accumulation in humans. Unlike others, the study will use POA as a dietary supplement, rather than complex oils, which contain a significant amount of saturated fat palmitic acid. Palmitic acid has known harmful effects on the body. Hence, eliminating palmitic acid from supplementation of POA might increase its benefits. This trial stems from the preclinical discoveries that POA acting as a fat hormone, has beneficial effects on the liver, muscle, vessels, and fat tissue. Supporting this, higher POA levels in humans have been shown to be correlated with a reduced risk of developing type-2 diabetes and cardiovascular diseases such as heart attacks. In animals, it has been observed that POA improves sugar metabolism in a number of mechanisms related to the liver and muscle. Based on these findings, the design of this study is a double-blind placebo-controlled trial that tests the effects of POA on insulin sensitivity of overweight and obese adult individuals with pre-diabetes.
The investigators are doing this study to learn more about how to prevent type 2 diabetes in teenage girls. The purpose of this study is to find out if taking part in a cognitive-behavioral therapy group, exercise training group, or a combination of cognitive-behavioral therapy and exercise training groups, decreases stress, improves mood, increases physical activity and physical fitness, and decreases insulin resistance among teenagers at risk for diabetes.
Acanthosis nigricans (AN) is increasing in its prevalence and is the most prevalent cutaneous manifestation in individuals with obesity. Insulin resistance or hyperinsulinemia is the main pathophysiological mechanism of obesity-related AN. However, the effect of laparoscopic sleeve gastrectomy (LSG) on insulin secretion pattern in Chinese morbidly obese patients with AN is unknown. In these study, the investigators aimed to explore the insulin secretion patterns in Chinese morbidly obese patients with Acanthosis nigricans (AN) and their alterations after LSG.
