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 SHORT trial compares the current standard optimization protocol to a shortened protocol in a randomized control trial.
Iron is an essential micronutrient for nearly all living organisms, including microbes. The adult human body contains approximately 3-5 g of iron (45-55 mg/kg of body weight in adult women and men, respectively). Iron-deficiency related anaemia (IDA) is a major public health problem that affects more than 2 billion people globally and this represents 24.8% of the world's population. According to World Health Organisation (WHO), iron deficiency is the most common cause of anaemia worldwide, with infants, children and women at higher risk, making it a global public health problem. Much iron deficiency is a result of poor iron dietary absorption since iron is poorly absorbed (~15%). Absorption inhibition factors (iron chelators) like phytate and tannins, found in tea and vegetables have been reported to act as potent iron uptake inhibitors. Despite its health benefits, tea-containing polyphenols (tannins) have been associated with reduction and disruption of iron absorption, acting as inhibitors of non-haem iron uptake, potentially resulting in poor iron status. However, most studies on the effect of tea on iron absorption are largely based on isotope-labelled single meal studies and animal studies. Iron is a requirement of many microorganisms, as such changes in iron availability can also have an impact on the gut microbiota. Long-term controlled human intervention studies to investigate the effect of tea on iron absorption and the effect on gut microbiota composition are scarce. In addition, the impact of dietary tannins on the gut microbiota is not understood. Thus, this proposed human intervention trial will investigate the combined effect of tea-tannins on iron status, inflammation and gut microbiota composition. This will be the first study to consider this combination of factors.
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.
Acute kidney injury (AKI) is experienced by 12% of patients following surgery and in up to 50% of patients following cardiac surgery. It is associated with an increased risk of death and prolonged stay in critical care after surgery. In addition to the patient impact, AKI costs the NHS alone between £434m and £620m per year. One way that AKI is diagnosed is by looking at a patient's urine output and checking how much is produced over time. If this value is too low for a patient, they are diagnosed with oliguria. Too many of these oliguria events leads to a diagnosis of AKI. The product to be tested (Stability UO) aims to reduce the number of patients who suffer three or more oliguria events after surgery by processing the data entered by the care team and providing the care team with additional information about the patient's risk of oliguria over the next six hours. Patients over 18 who present at Manchester University NHS Foundation Trust for non-emergency cardiac surgery will be screened and asked to consent to be randomised as part of the trial. Patients undergoing certain operations and those with unsuitable medical history (e.g. patients being treated for dialysis) will not be invited to participate. The randomisation will determine if their care team has access to the Stability UO software after surgery. While the care team looks after the patients in the cardiothoracic critical care unit (CTCCU) after surgery, they will enter that the patient's weight and amount of urine passed each hour into the software and review the output. The primary questions the study will answer is if there is a difference between number of oliguria events between the two groups of patients. The study is funded by the device manufacturer: Rinicare Ltd.
This study aims to investigate the utility of a combination of structured nurse led intervention and the use of Freestyle libre in adults with type 2 diabetes who have suffered an episode of severe hypoglycaemia in terms of mortality, unscheduled healthcare contacts and quality of life.
The aim of this study is to provide clinical evidence to determine if Whole Body Magnetic Resonance Imaging (WBMRI) with a novel technique called diffusion-weighted imaging (DWI) can improve current treatment for APC patients, allowing for early identification of disease progression or treatment response, hence facilitating clinical decision-making and leading to improvement in patient care. The IDT study includes two retrospective analyses and a single centre prospective observational study for APC patients.
Aortic disease is a life-threatening condition requires swift surgery or intervention. With modern techniques and vascular prostheses, still quite a few patients suffer surgery/intervention related complications such as suture line pseudoaneurysm, stent- induced re-entry tear, and aneurysmal expansion. Previous studies suggest that these complications may be related to the abnormal aortic motion pattern and biomechanical stress induced by vascular prostheses. The relationship between aortic motion changes and aortic adverse events after treatment still remains unclear. A dynamic protocol (multiphase contrast-enhanced ECG-gated) CT scan is able to measure the spatial motion of the ascending aorta, and finite element modelling is able to simulate both surgery or endovascular intervention and analyse the biomechanical interaction between vascular prostheses and tissue based on the patient-specific images. This project is aiming to explore and identify the interaction of 4D aortic motion and the biomechanical changes after surgery or endovascular treatment.
The study design is prospective, post-market, exploratory, single-centre, rate randomised, double-blinded (subject, evaluator blinded; programmer un-blinded). The study is designed to evaluate the wash-in and wash-out time of FAST (Fast Acting Sub-perception Therapy) at 90 Hz and various frequencies above and below 90 Hz. A prospective study design will eliminate the bias associated with case selection in a retrospective review and will ensure that identical procedures are followed for data capture and review. Randomization of rates will be used to minimise the sequence effects and the impact of carryover effects, as well as addressing issues that may be related to order effect. The electronic diary will be used to log the subjects' pain intensity and medication usage. Additionally, the numerical rating scale for measuring pain intensity is a validated measure and has been used in other randomized controlled trials to measure the outcomes of spinal cord stimulation (SCS). The electronic real-time NRS (Numerical rating score) recording will be used to log the subjects' pain intensity and time during wash-in evaluation session. This study aims to evaluate pain relief and wash-in/wash-out frequency sensitivity using FAST at different stimulation rates. The different randomization period included in the study design allows for comparing these treatments using one of the stimulation rates as an active control.
This study will recruit patients who are being prescribed Mepolizumab as part of their standard clinical care for the treatment of severe eosinophilic asthma. Over the course of their treatment, research data (questionnaires) and research samples (blood, breath and urine) will be collected in parallel to standard clinical measurements. The data and samples will be investigated to help better understand how Mepolizumab works, why it doesn't work in certain patients and why it works very well in others. This will help prescribers better identify patients that will benefit from Mepolizumab.
The purpose of this study is to gather early and mid- to long-term evidence to confirm the clinical performance, safety and use of the Clavicle Plate and Clavicle Hook Plate System. A minimum of 76 patients with clavicle fractures or dislocations of the AC joint surgically treated with any plate from the DPS VA-LCP Clavicle System will be enrolled in this observational post-market clinical investigation. Outcomes will be collected until up to 2 years after surgery.
