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.
Varicose veins of the leg often have superficial tributaries, which are often symptomatic and a major reason for coming to the doctor. When treating the main varicose vein inside the leg, some doctors prefer to remove these tributaries while others prefer to leave them. This trial aims to see if it is better to remove these veins at the time of the first laser procedure or better to leave them and only remove them when asked.
Investigators seek to observe the long term patterns of arrhythmias detected by permanent pacemakers.
The purpose of this study is to characterise the pharmacokinetics, safety and tolerability of RDC5 given as a single dose to healthy volunteers at a number of different dose levels
This research programme purports to test the effectiveness of two Transcranial Magnetic Stimulation (TMS) protocols (Repetitive high frequency protocol and Theta Burst protocol) in reducing the symptoms of depression. The study also uses Magnetic Resonance Imaging (MRI) scans to improve the localization of TMS targets.
Traumatic brain injury (TBI) is the most common cause of death and disability in young adults. Patients can experience significant problems with concentration, attention, and memory (so called 'cognitive impairments') following TBI. These cognitive impairments can drastically impact on a patient's well-being, and can lead to significant economic and social consequences. Roughly a quarter of TBI patients improve but an equal number deteriorate over time. The investigators know little about why patients vary so much in how they recover. Crucially, the investigators have no treatments to improve brain functioning or recovery after TBI. Trials investigating ways of protecting the brain just after injury have been disappointing. An alternative strategy, however, is to improve the function of brain regions that remain intact, but that function inefficiently after TBI. The investigators know that dopamine (a chemical in the brain) is known to influence many brain functions and the investigators know that pathways in the brain that use dopamine are affected by TBI. In humans, drugs that increase dopamine in the brain, such as methylphenidate, are sometimes used to enhance cognitive function after TBI, but the response to treatment can be highly variable between patients. Therefore, what is needed in the clinic is a way to target the use of these drugs to patients who are likely to respond. In a single centre study, the investigators will use SPECT (Single Photon Emission Tomography) imaging to measure dopamine levels in the brain. MRI (Magnetic Resonance Imaging) scans will assess brain structure and function. The investigators will test whether treatment with methylphenidate improves cognitive functions in TBI patients who have ongoing cognitive problems, whether the mechanism involves a normalisation of brain functioning and whether brain dopamine levels can predict the magnitude of any improvement in symptoms.
Clinical study that aims to evaluate a new strategy using the SYNTAX II Score calculator in the functional assessment of patients with new coronary 3-vessel-disease who undergo percutaneous coronary intervention (PCI)
AIMS To determine the effect of high and low sucrose diets on liver fat in healthy adult men with liver fat levels below 5%
Studies suggest that dietary omega-3 fatty acids influence the extent to which the time interval between each heart beat varies (heart rate variability; HRV). Low HRV is associated with increased risk of sudden cardiac death (SCD). The purpose of this research is to investigate the relationship between 24 hour parameters of HRV and blood omega-3 fatty acid levels in patients who have recently commenced haemodialysis.
An isolated bout of unaccustomed maximal eccentric exercise is associated with muscle force loss for 2-4 days, mild reversible muscle tenderness, and ultra-structural damage to the muscle fibers, elevation of muscle proteins in serum, and a detriment in range of motion. This single center, pilot study is designed to optimize conditions for the robust measurement of functional deficits after muscle damage and to identify markers of repair over 22 days to inform future intervention studies. The primary measure will be limb force (assessed electronically from the ergometer), previous studies have demonstrated that functional measures return fairly rapidly, usually between 2-4 days. Additionally, several biomarkers of muscle function will be measured over 22 days, as well as changes in protein synthesis in biopsy samples Deuterium-labelled water (D2O) will be consumed by all study participants from Day-3 through Day 22 to aid in quantifying newly synthesized proteins.
This is an open-label, 2 part study of pazopanib and/or MK 3475 in treatment naïve subjects with advanced RCC. Part 1 consists of a Phase I dose escalation of pazopanib + MK 3475 followed by an expansion cohort to determine the maximum tolerated regimen and the recommended Phase II dose. Part 2 is a randomized 3-arm Phase II study to evaluate the clinical efficacy and safety of pazopanib + MK 3475 as compared to single-agent pazopanib and single-agent MK 3475. The objectives of this Phase I/II study are to test the safety and tolerability of pazopanib in combination with MK 3475, and study the clinical efficacy of pazopanib in combination with MK 3475 in subjects with advanced RCC as compared with single-agent pazopanib and single-agent MK 3475. Following the Urgent Safety Measure (USM) released on February 09, 2017, the phase II (Part 2) portion of this study will not commence.
