There are about 25093 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.
A DDI study consisting of 3 parts conducted as an open label, fixed sequence study in healthy adult subjects.
Part A Multiple organ dysfunction syndrome is one of the main problems in critically ill patients. Several organ dysfunctions are routinely and systematically monitored in patients admitted to intensive care units. Gastrointestinal dysfunction is currently not included in multiple organ dysfunction scores and lacks a standardised approach. At the same time, investigators earlier studies have shown that gastrointestinal dysfunction plays an essential role in the course of illness in intensive care patients. A tool for measuring dysfunction is needed to enable future studies on interventions to improve gastrointestinal function. The GIDS (GastroIntestinal Dysfunction Score) combines different clinical signs and symptoms commonly observed and documented in patients in the ICU into a scoring system, allowing distinguishing between different grades of severity of dysfunction. The investigators will only use observations documented during the patient's stay in the intensive care unit without additional measurements and calculate gastrointestinal (GIDS) and other organ dysfunction scores. Part B Phosphate is an electrolyte commonly measured and often corrected, while the indications and clear guidance for correction are insufficiently studied. The results of this study will assist in specifying indications for the correction of phosphate levels better and refine the management strategies in the future. Only phosphate levels measured as part of routine care will be documented, no additional samples for study purposes will be taken, and the study will not influence the treatment of phosphate disorders.
Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), a major global public health concern, is commonly associated with obesity, diabetes, and dyslipidemia. MASLD is currently the most common cause of chronic liver disease affecting about 80% of people with obesity, ranging from simple fat deposits in the liver to Metabolic Dysfunction-Associated Steatohepatitis (MASH), cellular injury, advanced fibrosis, cirrhosis, or hepatocellular carcinoma. Patients with MASH are also at risk for cardiovascular disease and mortality. There is no universally approved medication for MASH. Weight loss remains the cornerstone of MASH treatment. Patients meeting the inclusion and exclusion criteria and who give informed consent will be enrolled in the trial and undergo the baseline liver biopsy (if none available). Approximately 120 patients with MASH and liver fibrosis (F1-F4 in baseline liver biopsy) will be randomized in a 1:1 ratio to metabolic surgery or medical treatment (incretin-based therapies ± other medical therapies for MASH) and followed for 2 years at which time a repeat liver biopsy will be performed for the assessment of the primary end point.
After a subarachnoid haemorrhage, complications are common and increase the overall rate of disability and death from the condition. Despite some advances in preventing, detecting and treating these complications, the rates of complications and associated risks remain high. Further research into ways to reduce complications of subarachnoid haemorrhage. Transcutaneous vagus nerve stimulation (tVNS) is a technique where a small handheld device is attached to an earpiece which stimulates the nerves to the ear. This is given for short periods and may help improve blood flow and reduce inflammation in the brain. The intervention has been safely used and licensed in seizures, headache and severe depression. This study will look to see if it is feasible and tolerable to have tVNS twice daily for 5 days after subarachnoid haemorrhage, and whether it can help reduce the risk of complications from subarachnoid haemorrhage. The participant will be randomly allocated to receive either tVNS or a dummy intervention, known as sham. The researchers will collect some personal and clinical details such as diagnosis, medications, age, blood test results, as well as some details about the subarachnoid haemorrhage. The researchers will also complete brief questionnaires with the participant to assess symptoms. They will take measurements of heart rate, pupil response, and brain activity using a cap. The participant will then be randomly allocated to either receive the tVNS or sham intervention. Next, the research team will apply the earpiece to their ear twice a day for 45 minutes, for a total of 5 days. At the end of the 5-day study period, the intervention will be complete. The researchers will arrange a follow-up meeting on discharge and at 6 weeks, to assess the participants symptoms and recovery. Previous studies have shown that tVNS is safe and well tolerated, including a recent review of tVNS studies which evaluated the side effects experienced by 1322 patients receiving tVNS. The main side effects include localised tingling/numbness/pain/redness around the ear (17%), headaches (3%), dizziness (1%), facial droop (1%), nausea (1%), nasal discharge (2%). Rarely, palpitations or a slow heart rate may occur. They will continue to receive full medical treatment and observation alongside the study. They are free to withdraw from this study if they find it too demanding on top of their other activities.
The use of photobiomodulation or low-level light therapy (LLLT) in the ophthalmic field stemmed from dermatology which has shown impact on skin blood flow and regeneration. There has been a rise in clinical interest with emerging evidence in the benefits of photobiomodulation in managing chronic inflammatory conditions such as dry eye disease including improvements in ocular discomfort symptoms, tear film stability and tear volume. Despite the observed clinical benefits, limited research has been done to compare photobiomodulation utilising different wavelengths, as most research on dry eye disease has focused on red wavelengths. It has been purported that blue wavelengths may disrupt microbial growth while red wavelengths stimulate energy production and hence increase heat in the affected tissues, although research into these differential impacts at the ocular surface and external eye has been limited. Hence, the aim of this exploratory clinical trial is to compare the impact of using LLLT incorporating red versus blue wavelengths on eyelid haemodynamics and microbiome, as well as conventional ocular surface measures of patients with dry eye disease and blepharitis (inflammation of the eyelids). Participants with dry eye disease, oil gland disruption and blepharitis will receive 3 treatments with these LLLT, each separted by 1 week apart, and followed up to 1 month after the final treatment session. Participants will be randomised to either of 3 groups: Red light only group, Red + Blue light group, or a sham treatment group.
Background: Arterial disease of the legs causes symptoms such as pain when walking and may ultimately lead to a leg amputation. Many older people with arterial disease of the legs also have problems with their thinking and memory. Blood flow in the brain may be altered in these people and may be a cause for memory and thinking problems. Aim: The aim of this project is to investigate whether people with arterial disease of the legs have altered blood flow in the brain causing problems with memory and thinking. Research plan: Twenty people with arterial disease of the legs causing pain while walking and twenty healthy people will have a series of non-invasive assessments. Arterial disease in the legs will be measured using ankle blood pressures before and after walking. Blood flow in the brain will be measured using ultrasound whilst performing memory and thinking tests. Results will be compared between the people with arterial disease in the legs and the healthy people to see if there are any differences in blood flow to the brain and memory and thinking. Benefits to society: This project will help determine if there is a link between arterial disease of the legs and memory and thinking problems caused by altered blood flow in the brain. It will enable future research in people with cognitive impairment caused by altered blood supply to the brain and to prevent confusion and further memory and thinking problems in people undergoing surgery for arterial disease of the legs.
The goal of this clinical investigation of a medical device is to test the safety of graphene based electrodes when used during surgery for resection of brain tumors. The main questions that it aims to answer are: - To understand the safety of these new electrodes when used during brain tumor surgery (primary objective); - To assess the quality of the brain signals recorded with the new electrodes, their ability to stimulate the brain, how stable their function is over the duration of an operation, and their suitability for use in the operating theatre (secondary objectives). Participants will undergo tumor surgery as usual with the study electrodes being tested alongside a standard monitoring system. If they are awake for part of their surgery they may be asked to complete specific tasks such as naming objects from a list modified for the study. They will be monitored subsequently for any complications including undergoing an additional MRI scan 6 weeks after their surgery.
This trial will assess the safety, feasibility, acceptability, usability and agreement with validated scales of an automated mood monitoring App (TrueBlue), in adult, perinatal participants (recruited between 12 weeks of pregnancy and 12 weeks post-partum), recruited across multiple sites in Nottinghamshire, United Kingdom (UK). An initial within-study pilot phase will assess key aspects of the study including recruitment rate, usability issues and a detailed understanding of any device related adverse events; prior to full recruitment of a total 125 participants over a total 14-month period.
Semaglutide is a glucagon-like peptide 1 receptor agonist (GLP-1RA). It is a safe medication approved for use in type-2 diabetes mellitus (T2DM) and obesity. Primarily, it works by counteracting insulin-resistance and inducing weight loss. It also acts on several other interconnected neurobiological, immunological (esp. inflammatory), endocrine-metabolic, and gut-brain axis processes that play a role in depressive symptoms. Its effects on cognition and energy are currently unknown. In this study we are using semaglutide as an experimental tool to further investigate these relationships.
THE PROBLEM: Patient Reported Experience Measures (PREMs) ask patients about their healthcare service experience. It gives them a voice to share their views. PREMs allow healthcare providers (HCPs) to see where care is good, and where they could improve. Vascular surgery is a surgical speciality looking after people's blood vessels (arteries and veins). There is no PREM available for vascular patients. The research team want to create a PREM for this patient group. WHY IT IS IMPORTANT: A PREM allows HCPs to record and understand patients' experiences of their treatment. It gives patients a way to provide feedback on their healthcare experience. PREMs can help HCPs make changes to patients' care, identifying areas of good practice and areas for improvement. The Welsh Government is keen to support the use of PREMs. AIMS: To develop a PREM specific to vascular surgery patients. RESEARCH PLAN: The research team will summarise the literature about PREMs in surgery. The research team will then run focus groups and interviews with patients and staff to create a 'draft' PREM for vascular patients in Wales. The 'draft' PREM will be translated into Welsh. In the second phase, a larger number of vascular patients (100-300 depending on how long the 'draft' PREM is) from hospitals across Wales will complete the questionnaire. Statistical tests will look at the results to see if the questionnaire works well to capture patients' experiences. Based on these results, small changes will be made to make the 'draft' PREM better. This will make sure the 'final PREM' is ready for widespread use in Wales and beyond. PATIENT AND PUBLIC INVOLVEMENT: The patients' experience team at CAVUHB has reviewed our patients' materials. Our research team includes PPI co-applicants (DC and AH). DC a double amputee who has had many vascular operations. DC has experience raising awareness about vascular disease through public forums like the Limbless Association Charity and BBC Radio Wales. AH has issues with her leg due to smoking and had a keyhole operation to help with that. She had some problems after the procedure This is her first time as a PPI representative. DC and AH supported our research design and will be steering group members. Also, our research focuses on giving patients a voice and will include patients across Wales. A diverse group of patients will be involved across all stages of the PREM development.
