Filter by:The current protocol plans to enroll participants with youth-onset Type 2 Diabetes (T2D) as well as obese and lean controls from the Renal-HEIR - Renal Hemodynamics, Energetics and Insulin Resistance in Youth Onset Type 2 Diabetes Study (n=100) [COMIRB #16-1752] in a prospective investigation that seeks to 1) define the changes in kidney function by gold standard techniques and energetics by functional Magnetic Resonance Imaging (MRI) in adolescents with and without T2D as they transition to young adulthood; 2) quantify kidney oxidative metabolism by 11C-acetate Positron Emission Tomography (PET) in a subset of participants who are ≥18 years of age with youth-onset T2D and/or obesity; 3) determine peripheral arterial stiffness by SphygmoCor. Mechanistic insight will be provided by transcriptomic analyses of repeat biopsies 3-years after their initial biopsy for eligible participants with youth-onset T2D, as well as molecular analysis of tissue obtained from J-wire endovascular biopsies. This study will also leverage this well-characterized cohort of youths to define youth-onset T2D-related changes in brain morphology and function by structural MRI and resting-state functional MRI and through the assessment of cognitive function (fluid and crystallized intelligence) using the NIH Toolbox Cognitive Battery (NIHTB-CB), as an exploratory objective. All enrollees in Renal-HEIR have consented to be contacted for future research opportunities.
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.
The aim of this project is to determine role for ET-1 in individuals with obesity.
We are evaluating whether intermittent use of continuous glucose monitors (CGMs) in addition to standard nutritional counseling and physical activity counseling is associated with improved metabolic health for youth with pre-diabetes (PD).
Patients with type 1 diabetes (T1D) and metabolic syndrome (MS) require high doses of insulin to achieve a glycemic control, due to insulin resistance (IR). The investigators identified the presence of metabolic syndrome and insulin resistance in patients with T1D in a population of southeast Mexico. The sampled population was recruited from the Diabetes Clinic of the Regional Hospital of High Specialty "Dr. Gustavo A. Rovirosa Pérez"; from August 2021 to February 2022, graduated physicians interviewed patients previously diagnosed with T1D. This study included patients older than 18 years and at least six months after being diagnosed with T1D. The interviewers excluded patients who did not attend regular consultations and those who did not agree to participate or to give a blood sample. A diabetologist evaluated and diagnosed all patients based on the World Health Organization (WHO) criteria. Fasting glucose, total cholesterol, HDL cholesterol, LDL cholesterol, and triacylglycerols were determined in blood serum using a Clinical Chemistry System from Random Access Diagnostics. The reasearch team determined glycated hemoglobin concentrations by an enzymatic immunoassay method.
Postoperative insulin resistance refers to the phenomenon that the body's glucose uptake stimulated by insulin is reduced due to stress effects such as trauma or the inhibitory effect of insulin on liver glucose output is weakened after surgery. There is a clear link between postoperative insulin resistance and poor perioperative prognosis. Therefore, exploring interventions to reduce postoperative stress insulin resistance, stabilize postoperative blood glucose, and reduce postoperative complications are clinical problems that need to be solved urgently. In recent years, research on branched-chain amino acids and metabolic diseases has become a hot spot. Studies have found that in the rat model, preoperatively given a high branched-chain amino acid diet can inhibit postoperative insulin resistance and stabilize blood glucose levels. This research plan is to try to add branched-chain amino acids before surgery to observe the occurrence of postoperative insulin resistance in patients.
Disordered sleep is a health issue with significant impacts on physical and psychological well-being that has increased in prevalence, but its impact on transgender adolescents has not been fully quantified. While there is found to be an impact of sex steroids on sleep, and sex-dependent differences in the impact of sleep duration and quality on insulin resistance (IR), there is limited available information regarding the impact of Gender Affirming Hormone Therapy (GAHT) for transgender individuals on sleep and IR. Our study aims to quantify the impacts of GAHT on sleep and IR in the pediatric transgender population as well as determine the degree of correlation of sleep to IR in this population.
Introduction. Insulin resistance (IR) accompanies practically half of children with obesity. This alteration is the border between what can be reversible or permanent. Among the comorbidities associated with IR are T2D and cardio and cerebrovascular diseases, which are the leading causes of death in Mexico. It has been said that the prevention of obesity rather than its treatment is the way to contain this problem. It has been proposed to supplement obese children with IR with ω-3 polyunsaturated fatty acids (PUFA) or ω-9 monounsaturated fatty acids (MUFA) to determine their ability to reverse these alterations. Objetive. To evaluate the effect of supplementing PUFA ω-3, PUFA ω-9 or both, on the change in anthropometric and metabolic parameters in obese children with IR. Methods. Clinical trial, randomized triple-blind, in which obese children with IR participated. Intervention. Three groups were integrated that received one of the following treatments for three months: Group 1: PUFA ω-3 1.8 g/day; Group 2: PUFA ω-3 0.9 g/day + PUFA ω-9 0.9 g/day (avocado oil). Group 3: MUFA ω-9 1.8 g/day. Tracing. For 2 more months he continued his clinical surveillance. Anthropometric and metabolic profile measurements were made at baseline, 3 and 5 months. Throughout the study, all three child groups received nutritional counseling, but no calorie-restricted diets or exercise programs were used.
Background: Lipodystrophy (LD) syndromes are a group of rare disorders that affect how a person s body can store and use fat tissue. Many people with LDs become severely insulin resistant. Some people are insulin resistant because of a variant in the insulin receptor gene. Insulin resistance causes many health problems. Objective: To learn if blocking the effects of growth hormone in the body will help people with severe insulin resistance. Eligibility: Adults aged 18 to 65 years with either a known variant in the insulin receptor gene or with a diagnosis of partial LD. Design: Participants will have 2 hospital stays, about 1 month apart. Each stay will be 3 or 4 nights. During each hospital stay, participants will have many tests. They will have a physical exam with blood tests. They will have all of their urine collected for a 24-hour period. They will have scans to measure their muscle, bone, and fat tissues. They will have tests to measure metabolism and insulin sensitivity. They may have an optional biopsy of fat tissue. During the first hospital visit, participants will learn how to give themselves shots of a drug (pegvisomant) that blocks growth hormone. The drug is injected under the skin. Participants will continue to give themselves these shots once a day at home. After the first hospital visit, participants will talk on the phone with members of the study team once each week. After 2 weeks they will have blood drawn for tests. Participants will stop the shots after the second hospital visit.
Healthy Life Centers (Norwegian, 'Frisklivssentralen') is a municipal service in Norway that aims to promote both physical and mental health, as well as to limit the development of non-communicable diseases. Previous research has shown that receiving follow-up from Healthy Life Centers has led to higher levels of daily physical activity, in addition to improved self-reported health and quality of life among the participants. However, there is a lack of studies that have examined what kind of physiological health effects can be expected from participating in the Healthy Life Center's follow-up. In this study, responses to the 12-week physical activity program of the Healthy Life Center will be compared with the responses in a negative control group that does not receive such follow-up. Both the intervention group and the reference group (the negative control group) will carry out the same tests and measurements before and after the 12 week period. The tests will include measurements of anthropometric variables (body height, body weight and waist circumference), body composition, arterial stiffness, resting blood pressure and blood variables (blood glucose, long-term blood glucose, blood lipid profile and inflammation markers), in addition to physical tests of mobility, balance, maximum aerobic capacity (maximal oxygen consumption) and maximum muscle strength. Questionnaires related to adherence to the Healthy Life Center follow-up, socio-demographic variables, eating and drinking habits, activity level, perceived physical fitness, motivation for exercise, and health-related quality of life will also be included.
