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 aims to observe participants' physical activity (PA) using a blinded multisensor physical activity monitor as they go about their typical daily physical activities across a 6-week time frame. Participants will also complete a subjective, self-reported, online form to denote structured activities undertaken.
A drop in blood pressure during anaesthesia for a surgical procedure has been associated with worse patient outcomes, including complications such as damage to the heart, brain and kidneys. Continuous blood pressure monitoring prior to the start of anaesthesia alerts the anaesthetist to drops in blood pressure and allows this to be treated promptly. This may help to avoid the complications described above. Continuous blood pressure monitoring is carried out by inserting a small plastic tube (cannula) into an artery. In this study, the investigators propose inserting a cannula into the radial artery in the wrist before a patient is anaesthetised for surgery. The usual technique for insertion of this cannula is for the anaesthetist to identify the site of the radial artery by feeling for an arterial pulse with the fingertips (palpation). An alternative technique for identification is to use ultrasound. Ultrasound creates a two-dimensional image of the area under the skin on a screen, enabling the operator to visualise the artery being targeted. This may reduce the number of cannulation attempts required, reducing patient discomfort.
Polycystic ovary syndrome (PCOS) affects 10% of all women and usually presents with irregular menstrual periods and difficulties conceiving. It is also a lifelong metabolic disorder and affected women have an increased risk of type 2 diabetes, high blood pressure, and heart disease. Increased blood levels of male hormones, also termed androgens, are found in most PCOS patients. Androgen excess appears to impair the ability of the body to respond to the sugar-regulating hormone insulin (also termed 'insulin resistance'). Androgens circulating in the blood in women with PCOS are comprised of classic androgens (for example testosterone), and the less-characterised 11-oxygenated androgen subclass that arises from the adrenal glands. The investigators have recently demonstrated that 11-oxygenated androgens make up the majority of circulating androgens in women with PCOS. In preliminary studies using minimally invasive adipose tissue sampling, the investigators have found that the fat tissue of women with PCOS overproduces classic androgens. This can lead directly to disturbances in the ability of fat cells to store fat effectively (lipotoxicity), resulting in insulin resistance and the consequent risk of liver damage. However, there are no published studies on in vivo androgen concentrations in the adipose tissue of women with PCOS. Furthermore, the scientific community do not have any information on whether adipose concentrations of 11-oxygenated androgens are also increased in women with PCOS. Research Questions The investigators aim to examine the metabolism of classic and 11-oxygenated androgens in detail in both circulations and in the adipose tissue of women with PCOS. The investigators will examine how precursor variants of both 11-oxygenated and classic androgens, which are converted by the body into active hormones, are broken down (metabolised) within the adipose tissue of women with PCOS. The investigators will also investigate if the 11-oxygenated androgens have a differential impact on metabolic function as compared to classic androgens. This will give important insights into the adipose tissue metabolome in women with PCOS, and how locally generated androgens impact on adipose tissue function and metabolic risk.
The overall aims of the study are: Aim 1: Estimate effect sizes: To estimate the effects of dCBT-I on insomnia symptoms compared to a control group (sleep hygiene education) and estimate the relationship between changes in insomnia symptoms and the reduction in migraines. Aim 2: Explore mechanisms of change: To explore the mechanisms underlining the change in migraine symptoms. Aim 3: Assess barriers to conducting a full-scale RCT: To collect data on recruitment pace and dropouts in both groups, which will help refine the methodology and maximise uptake and retention of a full-scale randomised control trial (RCT). The investigators will conduct qualitative interviews with a select number of participants and practitioners to identify motivators/barriers in uptake of a digitalised version of CBT-I.
This is a multicenter, randomized, open-label, Phase 3 study in participants with newly diagnosed multiple myeloma to evaluate the benefits of teclistamab in combination with lenalidomide and teclistamab alone versus lenalidomide alone as maintenance therapy after autologous stem cell transplant.
The purpose of this open-label 12-month extension study is to continue to characterize the long-term safety, efficacy and immunogenic profile of GSK3511294 (Depemokimab) in participants with severe asthma with an eosinophilic phenotype following completion of clinical studies 206713 or 213744.
This is the second study of AMT-130 in patients with early manifest HD and is designed as part of an integrated two-study phase I/II program under a single data safety monitoring board (DSMB) with staggered enrollment based upon continued demonstration of safety of AMT-130 administration. Cohort 3 participants will receive either high or low dose (1:1 randomization). Participants enrolled in Cohort 3 will also receive an immunosuppression regimen consisting of dexamethasone, sirolimus, and rituximab.
To use advanced imaging techniques, including MRI Brain and Spinal Cord, and MRI/PET Spinal Cord to provide an assessment of Degenerative Cervical Myelopathy to improve understanding of the pathophysiology and natural history of DCM.
The purpose of this study is to evaluate the efficacy and safety of JNJ-78934804 as compared to guselkumab and golimumab in participants with moderately to severely active ulcerative colitis who have had an inadequate initial response, loss of response, or intolerance to one or more approved advanced therapy.
The purpose of this study is to evaluate the efficacy of JNJ-78934804 at Week 48 compared to guselkumab and golimumab.
