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.
Background Psychosis is a mental health condition that affects around 3 in 100 people in their lifetime. Most treatments for psychosis target a brain chemical called dopamine but they don't work for everyone and don't address many of the symptoms. People with psychosis and people at risk of developing psychosis show differences in a part of the brain called the hippocampus, such as smaller size and increased activity. This hyperactivity may be associated with cognitive difficulties (thinking and memory). The basis of this hippocampal hyperactivity is thought to be a deficit in excitation and inhibition of brain cells. Excitation causes brain cells to send signals more frequently, and inhibition causes cells to send signals less frequently. A balance between these signals is important for the brain, including the hippocampus, to function properly. Approach Levetiracetam is a medication that is widely used to treat epilepsy and which helps balance excitation-inhibition in the brain. We will use brain imaging, using Magnetic Resonance Imaging (MRI), to test if levetiracetam can help reduce hippocampal hyperactivity, alter connectivity and change levels of brain chemicals in people who are at risk of developing psychosis. Participants (18-40 years), identified as at risk of psychosis through the Outreach and Support in South London (OASIS) teams, will attend an initial visit at the Institute of Psychiatry, Psychology & Neuroscience. This will involve questions about experiences and feelings, assessment of thinking and memory, and a blood test. They will then attend two scanning visits at the Centre for Neuroimaging Sciences, during which they will take capsules of either levetiracetam or placebo (in a randomised order) before having a 60 mins MRI scan. The MRI scan will look at blood flow to the hippocampus, resting activity, activity during a cognitive task and levels of brain chemicals. Funded by the Wellcome Trust and conducted by King's College London researchers, the study spans 2-3 months per participant. Impact Our study will provide important evidence about how levetiracetam affects brain function, and how this relates to cognition. This knowledge may lead to innovative approaches for understanding and treating psychosis early.
This study will assess the effect of 2 different colours of light on colour vision in adults with retinitis pigments (RP). Participants will be 18 years or above with a genetically confirmed molecular diagnosis of RP. After informed consent, participants will have their letter chart vision and colour vision measured in their study eye. They will then be they will be randomly allocated to one of 2 groups. The study team will not know which group they have been assigned to. Group 1 will be given a coloured-light hand-held torch and be asked to apply it to their study eye for 3 minutes at home each morning between 8 - 10 am for 28 days. Group 2 will be given a different colour hand-held torch and be asked to do the same. All participants will have their letter chart vision and colour vision measured at the end of study on day 28 (+ 7 days).
The CirrhoCare trial is a multi-centre, open label randomised controlled trial in patients with decompensated cirrhosis. The trial aims to investigate the clinical and cost-effectiveness of CirrhoCare digital home monitoring and management with current standard of care in these patients.
This clinical investigation is intended to demonstrate safety and effectiveness of the Volt™ Pulsed Field Ablation (PFA) Catheter Sensor Enabled™, the Volt™ PFA Generator, Agilis™ NxT Steerable Introducer Dual-Reach™, and EnSite™ X EP System EnSite™ Pulsed Field Ablation Module (for simplicity of reference this device collection will hereafter be referred to as the Volt™ PFA system) for the treatment of symptomatic, recurrent, drug-refractory paroxysmal and persistent atrial fibrillation.
Cholecystectomy is amongst the most common surgical operations performed worldwide. Surgical candidates are treated for biliary pathologies, such as biliary colic, cholecystitis and gallstone pancreatitis. In patients who are deemed fit for surgery, cholecystectomy can be performed under three main settings: (1) emergency setting at index admission; (2) elective setting with no previous admissions; or (3) delayed setting with one or more previous gallbladder-related admissions. The advent of laparoscopy fundamentally evolved biliary surgery and quickly became the "gold standard" approach. Recent multicentre collaborative studies have elucidated that the burden imposed on healthcare systems by laparoscopic cholecystectomies is primarily due to patient readmissions and complications arising from the operation, rather than perioperative mortality burden that was more commonly seen in open surgery. As a result, national and international societies have shifted their focus towards creating a culture of safety around this procedure, with the overarching goal of improving patient satisfaction and reducing hospital costs. The universal establishment of safe cholecystectomy is a complex process that relies not only on the operation itself, but also on various other factors such as promoting adequate training, improving hospital infrastructure, and enhancing perioperative patient care. There remains a paucity of evidence around the variations of safe provision of laparoscopic surgery for gallbladder disease internationally, including low- and middle-income countries. To bridge this knowledge gap, the Global Evaluation of Cholecystectomy Knowledge and Outcomes (GECKO) study (GlobalSurg 4) will be an international collaborative effort, delivered by the GlobalSurg network, that will allow contemporaneous data collection on the quality of cholecystectomies using measures covering infrastructure, care processes and outcomes. It will be disseminated via contacts from the National Institute for Health and Care Research (NIHR) Global Surgery unit, leading emergency general surgeons and specialist organisations.
The goal of this observational study is to learn about the impact of home monitoring in adults with cystic fibrosis. The main questions it aims to answer are: - how people with CF find using home monitoring equipment - to see if by using home monitoring data acute respiratory exacerbations (chest infections) can be detected earlier than standard care Participants will be provided with a range of home monitoring equipment - - hand held spirometer (lung function) - weighing scales - oximeter (blood oxygen levels) - activity and heart rate monitor to measure health at home several times a week. This information links to an app on a smartphone which the participant and clinicians can see.
Over 15 million people in England live with a long-term physical health condition. Low mood, loneliness and worry related to chronic illness are very common. In partnership with people with long-term conditions we have co-designed an online peer support platform to help people with health problems connect, support others, share experiences, and receive evidence-based information and advice on self-management. This study explores if the platform is feasible to implement and acceptable for people with long-term conditions experiencing mild depressive symptoms. Those allocated to the intervention arm will be invited to try out an online peer support platform with psychoeducational resources named "CommonGround". Those in the control arm will be guided to use the National Health Service NHS "Mental Health" webpages.
The aim of this research is to 1) test how the skin blood vessels and sweat glands function in women who experience hot flushes by using skin microdialysis to deliver small amounts of substances to the skin that cause increased skin blood flow and sweating, and 2) examine the structure of the skin blood vessels and sweat glands in the skin of women who experience hot flushes by taking a very small skin biopsy. Any changes in the function or structure of the skin blood vessels or sweat glands in women with hot flushes would increase our understanding of what causes hot flushes and help to design effective treatments.
