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.
The intention with the study is to have a better understanding of what happens to COPD patients' symptoms, lung function and markers of inflammation over 12 weeks. This information will increase the understanding of COPD and how to design new treatments for COPD in the future.
To compare the efficacy of Helicobacter pylori (HP) eradication with vonoprazan dual and triple therapy regimens versus lansoprazole triple therapy regimen in participants with HP infection, excluding participants who had a clarithromycin or amoxicillin resistant strain of HP at baseline.
The purpose of this study is to see if the study drug, tirzepatide administered once weekly, is safe and effective as a treatment for Nonalcoholic Steatohepatitis (NASH).
Mitochondrial diseases, estimated prevalence 1 in 4,300 adults, is caused by pathogenic mutations in genes finally encoding for mitochondrial proteins of the various enzyme complexes of the OXPHOS. Among these mutations, the 3243A>G nucleotide change in the mitochondrially encoded transfer RNALeu(UUR) leucine 1 gene (MT TL 1) is the most prevalent one. The OXPHOS dysfunction resulting from such mutations leads to increased production of reactive oxygen species (ROS), ultimately leading to irreversible oxidative damage of macromolecules, or to more selective and reversible redox modulation of cell signaling that may impact (adult) neurogenesis. Despite advances in the understanding of mitochondrial disorders, treatment options are extremely limited and, to date, largely supportive. Therefore, there is an urgent need for novel treatments. KH176, a new active pharmaceutical ingredient (API), is an orally bio-available small molecule under development for the treatment of these disorders (see Section 1.4). The current study will further evaluate the effect of KH176 in various cognitive domains and evaluate the effect of different doses of KH176 (See Section 1.5). In view of the growing recognition of the importance of mitochondrial function in maintaining cognitive processes in the brain, as well as the understanding of the safety profile and pharmacokinetics of KH176 following the two clinical studies described above, a more detailed study is indicated of the effects of KH176 in various cognitive domains, using the confirmed safe and well-tolerated KH176 dose of 100 mg bid, as well as a lower dose of 50 mg bid. The primary objective is an evaluation of KH176 in the attention domain of cognitive functioning, as assessed by the visual identification test score of the Cogstate computerised cognitive testing battery.
The purpose of this study is to determine if LCZ696 is safe, tolerable and can improve exercise capacity (via improved peak VO2) in non-obstructive HCM patient population over the course of 50 weeks of treatment.
During long surgical procedures under general anaesthetic, patients' body temperatures sometimes drop below 36°C. This is classified as hypothermia. These low temperatures are associated with medical complications and surgical wound infections. Despite various warming methods used during surgery a significant number of patients experience hypothermia during surgery. During laparoscopic procedures, standard practice is to use dry, unwarmed carbon dioxide (CO2) to inflate the peritoneum (insufflation). This may contribute to the risk of hypothermia and cause tissue desiccation. HumiGard is a CE marked device which humidifies and heats CO2 for insufflation. It is used together with other standard methods of keeping patients warm. Other studies suggest that the HumiGard device may prevent hypothermia, and help patients recover more quickly and with fewer problems after surgery. The investigators aim to find out whether the HumiGard device used with standard practice, gives better outcomes for patients, compared to standard care alone. To do this, the investigators first need to work out if such a study would be feasible to do and therefore whether a larger study can be done. A total of 40 patients who are having a laparoscopic colectomy operation (where a portion of their bowel is removed) will be recruited. Half will be treated with the HumiGard device plus standard care and half will be treated with a sham HumiGard device plus standard care. Patients will be allocated to one of these groups by random chance. Neither the patient, the surgeon, nor the assessor will know which treatment the patient is having. The investigators will measure patients' temperature during surgery, and also patients will be asked to complete a validated questionnaire to measure their quality of recovery and pain following surgery. The feasibility study will aim to highlight the most appropriate outcomes to be measured in a larger RCT.
The investigators performed a retrospective review of all patients undergoing appendicectomy from March-November 2018 using the online theatre database and discharge letters. CA was defined as patients with perforated or gangrenous appendicitis on histology. Patients were divided into 2 groups; Group 1 (G1) included patients with CA who had a drain inserted; Group 2 (G2) included patients with CA and no drain.
This is a qualitative interview study that aims to understand treatment burden in individuals who have experienced prostate or colorectal cancer treatment within the past five years. We intend to use patient and caregiver experiences to co-design interventions to optimise cancer aftercare. Treatment burden is the workload of healthcare for patients and the consequences of this workload on patient function. Treatment burden has been associated with negative outcomes in stroke, heart failure, diabetes, and renal failure. Cancer is increasingly becoming a chronic condition, and involves a variety of self-management tasks for patients and their caregivers. In this study investigators will investigate treatment burden in people after prostate and colorectal cancer. Investigators will seek to understand patient and caregiver perceptions about cancer aftercare, and ways that services could be redesigned and improved to reduce treatment burden, and improve patient outcomes. We will undertake a qualitative interview study, recruiting patients from general practices and oncology outpatient clinics who have completed potentially curative treatment for prostate or colorectal cancer, or who are on active surveillance or hormonal therapies for localised or locally advanced prostate cancer. We will purposively sample, to ensure that participants with comorbidities, those from lower socioeconomic groups, and rural dwellers are adequately represented. We will conduct interviews according to a schedule, informed by conceptual models of burden of treatment, Schwarzer's Health Action Process Approach, and Normalisation Process Theory. Interviews will be filmed and/or audio-recorded and transcribed. Framework and thematic analysis will be used to analyse and synthesise the data. Participants will be given the chance to comment on outputs and findings (triangulation). Investigators plan to use the results of this study, and excerpts from video interviews during co-design events, and to create new interventions to optimise aftercare for patients with prostate and colorectal cancer.
The human brain has a central role in regulating appetite and food intake. It integrates many metabolic, hedonic and trait-related signals that affect eating behaviour and determine when and how much we eat. The effects of non-nutritive sweeteners (NNS) that provide sweet taste with no calories on appetite, food intake thus weight status remain a subject of debate. In this study, the investigators aim to investigate whole brain response to the ingestion of beverages sweetened with caloric sugars (glucose, maltodextrin) or NNS (stevia) as well as neural substrates of attentional bias to food (pre-and post consumption) in healthy lean participants.
Lymphoma diagnosis often involves removal and biopsy of one or more lymph nodes. Many (around half) of these diagnostic procedures show that no cancer is present, hence unnecessary removal results in numerous side effects and complications. The procedure is also highly invasive. The investigators have already shown that it is possible to tell the difference between healthy and diseased tissue in the laboratory by looking at the light emitted by tissue when a low power laser is shone on to it. The investigators intend to use this technique, known as "Raman Spectroscopy" (RS) to tell if tissue in the node is cancerous or healthy. By combining RS with a fine needle, the technique can target tissues below the skin with minimal invasion. Our needle will provide the clinician with instant diagnosis without the delay and cost of a laboratory analysis by pathologists. The investigators have designed a probe that slides through a fine needle, guided by ultrasound, to the lymph node. The space between the two needles provides space for cell aspirate. The investigators propose to measure spectra from excess lymph node biopsy samples taken during standard routine diagnostic biopsy. The investigators are also interested to see if they can successfully extract a fine needle aspiration (FNA) biopsy sample using the device, as well as record a RS measurement. If successful this would ease clinical adoption as the study could run in parallel with existing standard routine clinical practice, using just one device. This study will evaluate the new device on half a lymph node that will be excised and snap-frozen during a routine surgical biopsy, to gather data for submission of approvals for an in-vivo study to follow.
