There are about 25435 clinical studies being (or have been) conducted in United Kingdom. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The main objective of this post-market surveillance study is to compare the subject's weight loss and quality of life, and device safety performance of the abiliti System and the adjustable gastric banding therapies in obese to morbidly obese subjects.
Exercise is an important part of a healthy lifestyle, and many people with Type 1 Diabetes like to take part in regular sport and exercise. The majority of people with Type 1 Diabetes are treated with a "basal bolus" insulin regimen, with background insulin provided by long-acting "basal" insulin doses, and "bolus" doses of short-acting insulin used to accompany food intake. Evidence shows that the main factor preventing people with diabetes from pursuing a more active lifestyle is fear of low blood glucose (hypoglycaemia). A previous study has shown that the type of background insulin affects the likelihood of an individual suffering hypoglycaemia during exercise and for 2 and a half hours afterwards. The aim of this study is to examine this further. The two most commonly used long-acting insulins, insulin glargine and insulin detemir, will be compared. Previous data suggests that there is a greater likelihood of hypoglycaemia with insulin glargine than insulin detemir. Exercise intensity can have an influence on the likelihood of hypoglycaemia, and in this previous study exercise intensity was measured using heart rate. This study will use a more formal definition of exercise intensity. The investigators will study blood glucose during exercise, but also metabolism as measured by hormones affecting blood glucose levels as well as markers of fat metabolism. The investigators will also use a continuous glucose monitoring system (CGMS) to consider hypoglycaemia on thei night following exercise as this is a recognised consequence of exercise in type 1 diabetes. The null hypothesis to be tested in this study is that there is no difference between the two insulins in their effect on blood glucose levels and metabolism during exercise and rates of nocturnal hypoglycaemia after exercise.
Patients attending the University Hospital Coventry UK with a broken wrist requiring an operation, will be invited to enter the study. At the first visit, they will have an xray of the wrist and will be asked to complete a number of questionnaires. The questions are to determine if they normally have pain in the wrist and how well they can perform their daily activities. The patient will then have an operation, and the fracture in the wrist will be held in the correct position with either a metal plate and screws or wires. At 6 weeks following the operation the patient will be reassessed and an xray will be taken. At 3 months, 6 months and 12 months after the operation patients will perform tests to assess the strength of their grip, pinch and movement of their wrist. In addition they will complete the the same questionnaires from their first visit. At the 12 month visit patients will have another xray.
Food allergy is a common problem, affecting 5-8% of the population. Peanut allergy causes reduced quality of life due to the perceived high risk of severe reactions. Patients rely on accurate labeling of both loose and pre-packed foods, but these are often ambiguous and unhelpful. There is a common conception that labeling is 'over-cautious'. Peanut-allergic consumers face increasingly restricted food choices in complying with this advice due, in part, to the proliferation of advisory labels such as 'may contain peanuts'. This contributes to the reduces quality of life of affected individuals. For industry to provide more accurate and helpful labeling, certain characteristics of the food-allergic population need to be defined. Firstly, the minimum 'eliciting dose' for the population has been estimated by studying large groups of peanut allergic patients who are challenged with peanut ingestion in increasing amounts. From these, an eliciting dose that provokes a reaction in 10% of the food-allergic population has been estimated at between six and 14mg of peanut protein. Translation of population eliciting doses (ED) into acceptable levels of allergen contamination for the population requires consideration of a 'safety factor'- to account for individual variability in dose threshold and severity. Data suggest such variability depends in part on extrinsic factors (exercise and sleep restriction). Each factor may have a different effect in scale and direction. The investigators are proposing a cross-over trial with 85 peanut-allergic adults who will each undergoing a baseline peanut challenge followed by repeat challenges with extrinsic factors applied, in random order (repeat baseline, +exercise and +sleep restriction). These data will further define ED for the UK population and a safety factor derived from shift in threshold, to inform industry and protect the allergic population.
The aim of this study is to assess which of two commonly used surgical procedures in the treatment of ovarian cysts called endometriomas (cutting out of the cyst - "cystectomy", or draining it and cauterising it's inner lining - "ablation") causes the least damage to the ovary and is therefore best at maintaining the future fertility potential of a patient.
Heart failure is a common, costly, disabling and potentially lethal condition. Despite well recognised and proven drug therapies, many patients remain breathless on exertion. A special pacemaker (cardiac resynchronisation therapy) may help improve symptoms of breathlessness and survival by restoring coordinated beating of the heart. However, despite careful planning and the knowledge of the most appropriate selection criteria, up to a third of patients do not get the desired beneficial effects after the pacemaker has been implanted. The implantation of the special pacemaker requires three leads (wires) to be inserted within the heart. Currently this is undertaken under X-ray guidance. Some patients may have scarring of the heart muscle due to previous heart attacks or their underlying condition. The X-ray technique cannot see this and therefore the doctor may implant the lead in such an area of scar tissue. Cardiac magnetic resonance imaging (CMR) can demonstrate these areas of scar. The study aims to investigate whether CMR can better predict where the wires should be placed. The CMR pictures will be taken before the patient has the special pacemaker implanted.
This study aims to test whether repeated sessions of tDCS result in long-lasting improvements in motor function in patients with chronic stroke.
The study will consist of pair of double-blind placebo-controlled trials of dietary supplementation with 15g/day FructoOligoSaccharide (FOS) for 7.5 weeks in patients with prostate carcinoma or 5 weeks in patients with cervical or endometrial carcinoma who are to undergo pelvic radiotherapy with intent to cure.
The PERFORM study is a pilot study investigating the feasibility and usefulness of performing a novel CT (Computed Tomography)scanning technique called Perfusion CT(CTP) as an addition to normal CT scanning in patients recruited to the FOXFIRE trial. All patients recruited to FOXFIRE at the Oxford Radcliffe Hospitals and University Hospitals of Leicester will be invited to take part. FOXFIRE is a national randomised controlled trial in which patients with unresectable liver tumours secondary to colorectal cancer will receive treatment with standard chemotherapy alone, or with chemotherapy in combination with an internal radiotherapy treatment which delivers radioactive particles(SIR-spheres) to the liver via its own blood supply (radioembolisation). In the FOXFIRE study a normal CT scan would usually be performed prior to the start of treatment and also three months after the commencement of treatment to assess the cancer's response to treatment, particularly whether the tumour has changed in size as a result of treatment. Perfusion CT gives the normal information on changes in tumour size but also assesses whether the blood flow to the cancer has changed, which may allow earlier identification of treatment success compared to normal CT scans. All patients consenting to participate in the PERFORM study will undergo four perfusion CT scans: one before the treatment starts, and one at the start of each of the second, third and fifth cycles of chemotherapy. The aim is to determine the feasibility of measuring tumour perfusion for data analysis using perfusion CT and to establish if the tumour perfusion pattern at baseline or shortly after the start of therapy can predict response to radioembolisation or chemotherapy. This research is funded by the National Institute for Health Research Biomedical Research Centre in Oxford and Oxfordshire Health Services Research Committee.
Overview: This open label, randomized, multi-centre study will enroll and treat 24 patients with refractory AAV. Aims: To determine the clinical response and severe adverse event rates associated with alemtuzumab therapy among patients with relapsing or refractory ANCA associated vasculitis (AAV). Hypothesis: Treatment with alemtuzumab induces sustained remission in AAV and will reduce immunosuppressive and steroid exposure.
