NCT ID: NCT01780740 Completed - Atrial Fibrillation Clinical Trials

Statin Therapy In Atrial Refractoriness and Reperfusion Injury

STARR
Start date: January 2012
Phase: Phase 4
Study type: Interventional

Patients with coronary artery disease are often prescribed drugs called statins because research has shown that, by lowering cholesterol, they reduce the risk of having a heart attack or other complications in the long-term. Experimental studies have suggested that statins may also have rapid anti-inflammatory, anti-oxidant and anti arrhythmic actions; however, whether these effects are of any benefit to patients remains to be proven. The purpose of STARR trial (Statin Therapy in Atrial Refractoriness and Reperfusion injury) is to evaluate whether a short course of a commonly used statin (atorvastatin, 80 mg once a day) decreases inflammation and stabilises electrical properties of the upper chamber of the heart in the post operative period of patients undergoing cardiac surgery on the heart-lung machine either for valve replacement and/or coronary artery bypass grafting. It will also examine whether this treatment can protect the heart from sustaining tissue damage when blood supply is restored after a period of ischaemia during the course of the surgery.In addition it will also explore the impact of this intervention on biology of the vessels used for bypass surgery and the fat tissue in the vicinity of the heart & blood vessels.

NCT ID: NCT01780298 Completed - COPD Clinical Trials

Chronic Obstructive Pulmonary Disease (COPD) Biomarker Identification Study

Start date: July 2011
Phase: N/A
Study type: Observational

Chronic obstructive pulmonary disease (COPD) is a common inflammatory disease of the airway affecting approximately 10% of individuals aged 40 years or more with a smoking history. The disease is characterized by an increase in numbers of airway white blood cells (neutrophils, lymphocytes and monocytes). Stimulation of white blood cells results in the release of different agents of inflammation. Some of these agents give an indication of the presence or severity of a disease when measured. This case control study will be conducted at The Heart Lung Centre, London, UK. The study aims to determine biomarkers for the differentiation of subjects with COPD (GOLD Stage 1-2 and who are current smokers with a ≥ 10 pack year smoking history) and three matched control groups: one of non-smoking subjects (never smoked), one of ex-smokers and one of current smokers. COPD subjects will be matched to the non-COPD subjects by gender, age and ethnicity. The study will include a range of physiological measurements including lung function, computerized tomography scans (CT scans), cardio pulmonary exercise test and computerized multichannel lung sounds analysis (Stethographics). In addition, lung inflammation will be assessed by cellular and molecular biomarkers using e.g. transcriptomics and proteomics technologies.

NCT ID: NCT01779245 Completed - Lipid Metabolism Clinical Trials

Effect of High-calcium Intake on Substrate Metabolism During Exercise

Start date: October 2012
Phase: N/A
Study type: Interventional

A high-calcium intake can accelerate fat loss under energy-restricted diets. Part of this may be due to a shift in substrate metabolism where there is an increase in the rate of fat oxidation. However, whether high-calcium intake can influence substrate metabolism during exercise is not known. Accordingly, we aim to investigate the effect of 2 weeks of high-calcium intake on substrate metabolism during exercise.

NCT ID: NCT01778348 Completed - Diabetes Mellitus Clinical Trials

Closing the Loop in Children and Adolescents With Type 1 Diabetes in the Home Setting

APCam08
Start date: December 2013
Phase: Phase 2
Study type: Interventional

Type 1 diabetes (T1D) is one of the most common chronic childhood diseases requiring lifelong insulin therapy. Children and adolescents with T1D need regular insulin injections or the continuous insulin delivery using an insulin pump in order to keep blood glucose levels normal. We know that keeping blood sugars in the normal range will help prevent longterm diabetes-related complications involving the eyes, kidneys and heart. However, achieving treatment goals can be very difficult as the tighter we try to control blood glucose levels, the greater the risk to develop symptoms and signs of low glucose levels (hypoglycaemia). This is a particular problem at night and one solution is to develop a system whereby the amount of insulin injected is controlled by a computer and is very closely matched to the blood sugar levels on a continuous basis. This can be achieved by what is known as a "closed-loop system" where a small glucose sensor placed under the skin communicates with a computer containing an algorithm that drives an insulin pump. We have been testing such a system in Cambridge over the last five years in children and have found that this system is effective at maintaining tight glucose control and preventing nocturnal hypoglycaemia. More recently the system has been tested in real life conditions in the home setting for three weeks during a pilot single-centre study. The next step is to extend the evaluation of closed-loop over a prolonged period of three months. In the present study we are planning to study 24 young people aged 6-18 years on insulin pump therapy. During three months glucose will be controlled by the computer and during the other three months the subjects will make their own adjustments to the insulin therapy using real-time continuous glucose monitoring. We aim to determine the effect of the computer algorithm in keeping glucose levels between 3.9 and 8 mmol/L (normal levels). Safety evaluation comprises assessment of the frequency of severe hypoglycaemic episodes. Participants' response to the use of the system in terms of lifestyle change, daily diabetes management and fear of hypoglycaemia will be assessed. We will also test for longer term glucose control by measuring glycated haemoglobin (HbA1c).

NCT ID: NCT01777893 Completed - Obesity Clinical Trials

Effect of Diet and Physical Activity on Incidence of Type 2 Diabetes

PREVIEW
Start date: June 2013
Phase: N/A
Study type: Interventional

Type-2 diabetes is one of the fastest growing chronic diseases worldwide. This trend is mainly driven by a global increase in the prevalence of obesity. The PREVIEW study has been initiated to find out the most effective lifestyle-components (diet and physical activity) in the prevention of Type-2 diabetes. The project consists of a randomized lifestyle-intervention with the more specific aim to determine the preventative impact of a high-protein and low-GI diet in combination with moderate or high intensity physical activity compared with a moderate-protein and moderate GI diet in combination with the same activity levels on the incidence of Type-2 diabetes in predisposed, pre-diabetic children, young and older adults. The trial will be performed in 6 EU countries (Bulgaria, Denmark, Finland, Spain, Netherlands, UK) and Australia and New Zealand. A total of 2,500 overweight or obese adult participants (25-70 y) as well as 150 children and adolescents aged 10—18 y) will be recruited. All adult participants are first treated by a low-calorie diet for 8 weeks, with an aim to reach ≥ 8% weight reduction. Children and adolescents are treated separately with a conventional weight-reduction diet, with-out a specific aim for absolute weight loss. The adult participants are randomized into two different diet interventions and two exercise interventions for a total of 148 weeks. This period aims at preventing Type-2 diabetes by weight-maintenance (prevention of relapse in reduced body weight) and by independent metabolic effects of diet and physical activity. The primary endpoint of the study is the incidence of Type-2 diabetes in the adults during 3 years (156 weeks) according to diet (high protein/low-GI versus moderate protein/moderate-GI, adjusted for physical activity), based on a 75 g oral glucose tolerance test and/or HbA1c. For children and adolescents: Change in insulin resistance at 2 years after randomization to high protein versus moderate protein diet, measured by insulin resistance analyzed by the homeostatic model (HOMA-IR) as well as physiological improvement of health with respect to pre-diabetic characteristics. Our hypothesis is that a high-protein, low-GI diet will be superior in preventing type-2 diabetes, compared with a moderate protein, moderate GI diet, and that high-intensity physical activity will be superior compared to moderate-intensity physical activity.
