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.
Prospective observational study to compare sensitivity of 3T functional Magnetic Resonance Imaging (3T fMRI) at diagnosing Parkinson's Disease (PD) against the benchmark DaTScan diagnostic test and clinical diagnosis at follow up.
This study investigates the use of virtual environments presented on a head mounted display for the rehabilitation of those suffering with visual vertigo. The control group and treatment groups will be presented with two different sets of environments and be given the same head and eye exercises to complete within the environment. They will also be provided with at home exercises to complete.
Individuals receiving dialysis are at risk of heart failure and heart related death. There is an urgent need for treatments that reduce the risk of these problems in patients that require dialysis. Spironolactone is a pill used to prevent heart failure and related deaths in patients that do not require dialysis. It works by blocking a hormone (aldosterone) in your body that causes high blood pressure and can damage the heart. Although spironolactone is very effective in patients that do not require dialysis, we do not know if spironolactone is effective in dialysis patients. Our research will help determine if spironolactone reduces heart failure and heart related deaths in dialysis patients. The purpose of this study is to determine if spironolactone reduces death or hospitalization for heart failure and is well tolerated in patients that require dialysis.
Hypertension, also known as high blood pressure, is a chronic medical condition, in which the blood pressure is elevated. This is a common condition, which can lead to severe complications such as cardiovascular disease, heart attack, stroke and kidney disease, if not detected and treated early. Accumulating evidence suggests that the incidence of hypertension varies according to age, ethnicity and obesity. In order to obtain an in-depth knowledge of the pathophysiological mechanisms of hypertension, we aim to investigate the haemodynamic and biochemical correlates of elevated blood pressure across the adult age-span, and determine the extent to which body size and ethnicity impact on these associations. We also wish to investigate the impact of hypertension on key target organs (end-organ damage). The primary objective of this study is to compare the mechanisms regulating blood pressure in hypertensive and non-hypertensive participants across the adult age span, and to assess the influence of body mass index and ethnic background on these mechanisms. Secondary objectives are to investigate the association between blood pressure and cardiovascular physiology across the adult age span at rest and during sub-maximal exercise and to investigate the impact of blood pressure haemodynamics on key organs including the arteries and heart by assessing end-organ damage such as endothelial function, arterial structure and left ventricular mass/function. This study will be a combined case-control and cross-sectional study describing the procedures and time commitment required to investigate our scientific aims. This is a single centre study that will be conducted in a secondary care environment. Both male and females aged 18 and over and that are able provide informed consent will be considered for this study. People who are pregnant, currently receiving dialysis, illness with a life expectancy <1 year, current active malignancy and cannot provide informed consent are ineligible for this study. The study will be open for five years and each patient will complete a maximum of four visits in a 12 month period. Participants will complete a variety of non-invasive physiological assessments of their cardiovascular system and lung function. There will be some minimally invasive procedures completed, including a blood test and assessment of small artery endothelial function which involves insertion of a small needle under local anesthetic.
Studying the airway microenvironment in patients undergoing surgical and bronchoscopic interventions for COPD
Studying the microbiome of the lung in patients treated with endobronchial lung volume reduction coils for emphysema
A single arm pilot study of lung volume reduction in severe emphysema using bronchoscopic autologous blood instillation in combination with intra-bronchial valves.
There is a rapidly escalating epidemic of obesity and type 2 diabetes across the world, with the fastest rise occurring in low- and middle-income countries. India not only has one of the highest rates in the world, but the disease starts at a younger age and lower levels of body weight than in UK white caucasians. Among city-dwelling Indians, approximately 8% of people aged 30-40 years already have diabetes. This is creating a heavy burden of disease and disability, and an intolerable economic burden through medical costs and lost earnings. Until now, efforts to prevent diabetes have mainly focussed on modifying the diet, lifestyle and activity of at-risk adults (for example those who are overweight, have a family history of diabetes or already have high blood sugar). However, recent research has indicated that factors acting in early life (during development in the womb) place an individual at risk of later diabetes. These include maternal malnutrition and low birthweight, and diabetes in the mother during pregnancy. Our research has shown that Indian mothers often have low vitamin B12 levels, which in turn causes high blood levels of a harmful metabolite (homocysteine). We have shown that these mothers get more diabetes in pregnancy. Their children are more likely to born with a low birth weight, and develop more body fat and higher plasma insulin levels during childhood, which are signs of higher diabetes risk in later life. The risk is increased further if the mother has normal or high status for another B vitamin, folate. Thus, we have shown, for the first time a link between a specific nutritional deficiency in the mother and diabetes risk in the next generation. One possible mechanism for the effect of maternal nutrition on risk of diabetes in her children is through epigenetic effects, whereby the nutritional environment during early development affects the switches that control gene expression. Since these switches are passed on via either parent, we think it is possible that paternal vitamin B12 status could also be important.
Historically, cancer research has been limited by sample acquisition in late stage disease, often restricted to single sites of disease with limited parallel clinical data collection in terms of prior therapy exposure. The PEACE study is intended to facilitate tissue donation from multiple tumour sites in the post-mortem setting and enable future research using samples collected at post-mortem within different disciplines related to cancer research.
LQD is a multicentre randomised clinical trial comparing the clinical and cost effectiveness of lithium versus quetiapine when used as add-on therapies to antidepressant medication for patients with treatment resistant depression. The Lithium versus Quetiapine in Depression (LQD) study will assess patients over 12 months to establish which (if any) treatment is more likely to improve TRD over a long duration of time. Professor Anthony Cleare is the Chief Investigator and recruitment began in November 2016.
