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.
Capillary blood sample results are compared to venous blood results
In pilot studies the investigators have shown that subcutaneous adipose tissue (SAT) from patients with reduced ejection fraction heart failure (HFrEF) and type 2 diabetes mellitus (T2DM) is dysfunctional. Endothelial cells from the adipose tissue from these patients are senescent and have deleterious effects on healthy human subcutaneous adipocytes, including increasing expression of IL-6 (gene and protein) and reducing glucose uptake. Digoxin, a well-established treatment for HFrEF, selectively clears these senescent endothelial cells and prevents adipocyte dysfunction. This study will examine the effect of digoxin on adipose tissue on the burden of senescent cells.
Rheumatoid arthritis is an autoimmune condition, causing inflammation and pain. Yet pain may persist even when inflammation has been treated. This residual pain, called nociplastic pain, has symptoms of a chronic pain condition called fibromyalgia. There are few effective therapies to address this residual pain. Published literature shows that fibromyalgia can be treated by neurofeedback, a noninvasive method that is based on the voluntary modulation of cortical activity. In this pilot study, the investigators want to test the effect of neurofeedback on the fibromyalgia component of pain in rheumatoid arthritis, and also to investigate its effects on related symptoms such as fatigue and sleep disturbance.
Acute kidney injury (AKI) is a common complication of septic shock and together these conditions carry a high mortality risk. In septic patients who develop severe AKI renal cortical perfusion is deficient despite normal macrovascular organ blood flow. This intra-renal perfusion abnormality may be amenable to pharmacological manipulation, which may offer mechanistic insight into the pathophysiology of septic AKI. The aim of the current study is to investigate the effects of vasopressin and angiotensin II on renal microcirculatory perfusion in a cohort of patients with septic shock.
This clinical trial aims to explore the effect of Vitamin B6 supplementation on anxiety sensory hyperreactivity in autistic adults. Researchers will compare a placebo group to high-dose Vitamin-B6 to see if vitamin B6 reduce anxiety and sensory reactivity differences in autism.
This study is a single-centre prospective observational cohort study designed to assess and compare the sensitivity and specificity of a Lunit INSIGHT MMG assisted human reading to the standard care double human reading process within mammography review at a "one-stop" breast clinic (non-inferiority study). The current imaging reporting process is a sequential double read of mammography and ultrasound (if available) images, by consultant radiologists or radiographers. The first reader produces a report which is then sent to the second reader who reviews it. If the second reader agrees with the first, this is reflected in the second reader's report which translates into a decision for further actionÍž in the event of disagreement, a third reader arbitrates and produces the final report. In the past, breast clinics have had to resort to single reader reporting due to staff shortages and high demand. This results in delays to any further assessments that may be required. It is worth noting however that despite difficulties in meeting the target, the current clinical pathway has proven to be cost effective. The Lunit INSIGHT MMG tool could generate benefits and potential efficiencies if it were introduced to the clinical service as an assistant reader within the mammography reporting process, by replacing one of the two human readers in the current standard of care. Before this can be assessed however, its non-inferiority in combination with a human reader in comparison to standard of care (double human reading) must first be established. This study will aim to address this issue in the first instance, maintaining standard of care for all patients seen within the 2 week wait pathway, by introducing the use of Lunit INSIGHT MMG into one of two arms within this prospective, observational parallel cohort study.
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 Parasitic Ulcer Treatment Trial (PUTT) is a multi-center, parallel-group, randomized clinical trial. The purpose of this study is to determine whether including topical corticosteroids in a regimen for acanthamoeba keratitis (AK) will improve vision. Patients presenting to all enrollment centers with evidence of acanthamoeba keratitis will be eligible for the trial if there is evidence of ocular inflammation after 4 weeks of anti-amoebic therapy. Those who agree to participate will be randomized to one of two treatment groups: - Group 1: Topical corticosteroid - Group 2: Topical placebo
The goal of this clinical trial is to evaluate two treatment strategies in patients with chronic atrial fibrillation and heart failure, who are eligible for atrial fibrillation ablation. Patients will be randomized to either atrial fibrillation ablation or to implantation of a pacemaker with conduction system pacing followed by atrioventricular node ablation. The effect of treatment allocation on total mortality, cardiovascular hospitalization and heart failure hospitalization will be compared.
