Filter by:BACKGROUND: The relation between gut microbiota and obesity originates from animal studies, showing that the change of gut microbiota can induce changes in both insulin resistance and body composition. In addition, these studies have shown changes in gut permeability inducing a pro-inflammatory state, changes in adipose tissue function and inflammation, effects on energy harvesting and metabolism, skeletal muscle fatty acid partitioning and fat oxidation. Human data is lacking, although several studies suggested that the composition of the gut microbiota differs between lean and obese, and between diabetic and non-diabetic individuals. OBJECTIVE: To provide insight in the physiological significance and underlying mechanisms involved in the relation between gut microbiota, energy balance and insulin sensitivity in overweight men with impaired glucose homeostasis.
In this study, consecutive patients with cryptogenic cirrhosis (NASH-related cirrhosis), coming to ILBS (Institute of Liver & Biliary Sciences) OPD (Out patient Department) or getting admitted in the ward will be enrolled on fulfillment of inclusion/exclusion criteria and consent of the patient. These patients will be randomised to either metformin arm or conventional treatment arm. After enrollment these subjects will be monitored every three monthly for total of 12 months or till the primary endpoint is achieved. At the end of the study, outcome will be measured appropriately.
The investigators will study the influence of fat cell size/number and adipose function on weight development over very long time periods (years). By comparing fat biopsies obtained at baseline and after >7 years, the investigators will determine the association between adipose morphology/function and changes in weight or development of cardiometabolic complications (e.g. insulin resistance, type 2 diabetes, dyslipidemia and hypertension).
Thickening of the heart muscle (left ventricle) known medically as Left Ventricular Hypertrophy (LVH) is very common in patients with heart disease. This increases risk of cerebrovascular/cardiovascular event. LVH is asymptomatic and managed by the use of medication to control blood pressure, however LVH may be seen in normotensive patients where factors such as obesity and insulin resistance are present. Insulin resistance is a condition where although the body produces insulin it is unable to utilize it effectively. Metformin, a drug used to treat diabetes, can reduce insulin resistance and cause weight loss, it may therefore improve LVH. This study will investigate the ability of metformin to reduce LVH in patients with heart disease, this may be a novel way forward in the risk reduction of cerebrovascular/cardiovascular events. Participants will be identified throughout NHS Tayside, those eligible will be randomly allocated to either metformin or a dummy medication (placebo) and will receive one year of treatment. At the beginning of the study, the thickness of the heart muscle will be measured by ultrasound scan and cardiac Magnetic Resonance Imaging (cMRI). We will also perform non-invasive tests to measure blood vessel function. These tests will be repeated after one year. At the end of the study, we will investigate the difference between placebo treatment and metformin treatment. This study is funded by the British Heart Foundation.
Obesity is a growing problem in East London and every other woman who enters pregnancy is obese or overweight. In addition to obesity, other metabolic risk factors such as raised lipids, high blood pressure and diabetes increase pregnancy related complications such as preeclampsia and long term problems such as heart diseases, stroke and death. Preeclampsia, presenting as hypertension and proteinuria is a leading cause of maternal and fetal mortality and morbidity. Interventions that reduce cardiovascular events by modifying risk factors also have the potential to reduce the risk of preeclampsia. The investigators work funded by the National Institute of Health Research (NIHR) in the UK showed that dietary interventions in obese pregnant women may reduce the risk of preeclampsia. The investigators propose to show that pregnant women with metabolic risk factors derive the most benefit from a simple, targeted intervention based on Mediterranean dietary pattern to reduce the risk of maternal and fetal complications . Women with the risk factors (1230 women) will be randomly allocated to dietary intervention or usual antenatal dietary advice and the risk of maternal and fetal complications will be evaluated. The remaining eligible women who are consented for lipid tests, but do not have metabolic risk factors, will be followed up for outcome data only. Diet based interventions, especially those based on a Mediterranean dietary pattern has a potential to reduce the risk of preeclampsia. In the investigators study, pregnant mothers with risk factors will be randomly allocated to either a dietary invention or usual antenatal care and they will assess their composite maternal (pre-eclampsia or gestational diabetes) and fetal (stillbirth, small for gestational age or admission to neonatal intensive care unit) outcomes. The investigators will tailor the intervention to suit the individual needs of the mother and provide nuts and olive oil to improve compliance. The study will be undertaken across the three maternity units at Barts Health NHS Trust, which delivers 17,000 women/year and two other maternity units in England. The study is supported by the office of the Mayor of Tower Hamlets which will facilitate the involvement of grassroots workers to promote recruitment and uptake of the intervention.
The current project is designed as a 30-day pilot trial to demonstrate the safety and tolerability of resveratrol therapy in overweight adolescents to decrease liver fat, and improve insulin sensitivity to prevent type 2 diabetes.
Changes in insulin resistance in healthy volunteers with normal body weight (BMI 18-25) after 14 days of STRIBILD®-, Truvada®/Kaletra® or Truvada®/Prezista®/Norvir® intake, measured by hyperinsulinemic euglycemic clamp.
This study will look into insulin sensitivity (how the body responds to insulin) and effects of meals on type 2 diabetics comparing insulin peglispro to insulin glargine. The study has two treatment periods, each of which will last about four weeks. One drug (insulin peglispro or insulin glargine) will be administered in each period. Participants will receive both drugs during the study. Participants may remain on stable dose metformin, as prescribed by their personal physician.
The purpose of this study is to examine the pathophysiology of insulin resistance and the relation to the metabolic syndrome in humans.
Stretching and flexibility exercise such as yoga and functional resistance exercise are two forms of exercise that are growing in popularity. However, they have not been scientifically tested to demonstrate their ability to improve body composition, fitness, heart and metabolic health, and mood state in overweight/obese women. The investigators hypothesize that during an 11 week intervention, both forms of exercise will improve body composition, heart and metabolic health and mood state.
