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.
This study will compare two different surgical methods used in total knee replacement with the Unity Total Knee Replacement System. The study will evaluate these two methods based on patients' ability to perform various tasks prior to surgery and at 4 time points during the first 12 months after surgery.
This is a single arm, single centre imaging study which will be offered to all consecutive, eligible patients receiving radical chemoradiation therapy (CRT) for anal cancer within Oxford University Hospitals. Investigations - Dynamic contrast enhanced magnetic resonance imaging (DCE MRI) - Diffusion weighted magnetic resonance imaging (DWI MRI) - MRI scan designed to measure the T1 or produce T1-weighed images (T1 MRI) - MRI scan designed to measure the T2* or produce T2*-weighed images (T2* MRI) - Perfusion computed tomography (pCT) - Fludeoxyglucose positron emission tomography (FDG PET/CT) Study Design: Observational Target Population: Patients undergoing radical CRT for anal cancer in Oxford University Hospitals National Health Service (NHS) Trust. Duration on study: Patients should be on study for a maximum of 5 months. Patient care post-trial: Follow up as per local standard. No. of Study Site(s): Single Centre, United Kingdon (UK) End of study: Last Patient, last assessment of response. Patients should be on study for a maximum of 5 months.
This research project is designed to find out whether people who suffer repeated urinary tract infections (UTI) related to the need to empty their bladders intermittently with a fine plastic tube (catheter); a process called clean intermittent self-catheterisation (CISC), benefit from taking continuous daily low-dose antibiotics (antibiotic prophylaxis). The investigators estimate that about 40,000 people in the United Kingdom need to use CISC regularly to empty their bladder either because of nerve damage such as multiple sclerosis or because of failure of the bladder muscle to contract, and of these about 25% (10,000 people) suffer frequent UTI. One way to reduce this problem may be to take a small daily dose of antibiotics and the study aims to find out whether such treatment is effective and worthwhile both for the people who suffer the problem and for the National Health Service (NHS). The two options to be compared in the trial are firstly, a once daily preventive dose (prophylaxis) of an antibiotic routinely used for this purpose (either nitrofurantoin or trimethoprim or cefalexin), and secondly no prophylaxis. The investigators think that an overall decrease of 20% or more in the frequency of UTI would be large enough for future patients using CISC who get troublesome recurrent UTIs to be offered antibiotic prophylaxis routinely. The investigators will also assess any harm caused by continuous use of antibiotics, particularly side effects for those people taking them and changes in the resistance of bacteria to these antibiotics. The investigators can then work out whether the balance between the benefits and harms make the use of prophylaxis worthwhile to people carrying out CISC and for the NHS as a whole.
The study will include an implantation of the iTind device and 4 follow up visits up to 12 months after the implantation.
Losing weight before undergoing Roux-en-Y gastric bypass (RYGB) surgery may reduce liver fat content and size thereby improving surgical outcomes. This study aims to investigate whether a 2-week or 6-week pre-operative liquid formula low-calorie diet (LCD) reduces liver fat further than a conventional food diet prior to RYGB using magnetic resonance imaging (MRI). The hypothesis is that the 2-week and 6-week liquid formula LCD will reduce liver fat further than the conventional food pre-operative diet.
Cardiovascular disease (CVD) is the leading cause of death in women. Premenopausal women have a lower risk of CVD compared with men of a similar age. However, the incidence of CVD increases greatly after the menopause. The risk of heart disease is strongly associated with the health of an individual's blood vessels. It is thought that changes to the type of fat the investigators eat in their diet may affect the normal functioning and elasticity of the blood vessels, as well as affect cholesterol levels in the blood. Types of fat in the diet include monounsaturated fats (found mainly in olive oil), n-6 polyunsaturated fats (found mainly in sunflower oil) and saturated fats (found mainly in dairy products, such as butter and cheese). Since the investigators are in the fed (or postprandial) state for up to 18 hours of the day, it is important to see how these different fats affect the investigators blood vessels and blood fats over the course of the day after eating a meal. The aim of this study is to determine how consuming meals rich in saturated fats, n-6 polyunsaturated fats or monounsaturated fats influence the normal functioning and elasticity of the blood vessels throughout the day in postmenopausal women. A secondary aim is to determine the effects of these different dietary fats on a range of accepted heart disease risk markers including circulating levels of fats (lipids) and glucose in the blood.
The purpose of the study is to test how well magnetic resonance imaging (MRI) can measure whole gut transit time in people with constipation, and how readily it can detect a change in transit time induced by taking a dietary supplement with laxative effects.The investigators expect to demonstrate that ispaghula (psyllium) accelerates movement of matter through the intestinal tract. The investigators will also assess whether a change in gut bacteria and the chemicals that they release can be detected.
This study aims to test the feasibility of a physical activity intervention called the Steps To Active Kids (STAK) programme in children aged 9 - 11 years with Type 1 Diabetes Mellitus (T1DM).
This is a first time in man (FTIM), Phase I study to determine the Maximum Tolerated Dose, Recommended Phase 2 Dose, safety, tolerability and Pharmacokinetics of AZD5312. This is a multicentre study with sites in the United States and United Kingdom. Approximately 90 patients are expected to be enrolled in this study. The study involves two parts, Part A, Dose Escalation and Part B, Dose Expansion.
The Department of Health has recently announced the implementation of annual vaccination for all those aged 18 years and under, with live attenuated influenza vaccine (LAIV), which is delivered as a nasal spray. This study seeks primarily to measure antibody responses to the LAIV vaccination over three subsequent years and will involve six blood samples, six dried blood spots (taken from the end of the blood sample needle) and six oral fluid samples - before and three weeks after each vaccination each year. These samples will allow us to assess how the immune system responds to the vaccinations in terms of the antibodies that are present.
