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.
Prospective cohort study to test the hypothesis that patients identified with severe aortic stenosis are under-diagnosed and under-treated. Such patients shall be identified by auscultation or target echocardiography during flu vaccination. The hypothesis is that this will increase detection of aortic stenosis in the community.
The primary purpose of phase 1 portion of this study is to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of H3B-6545 in women with locally advanced or metastatic estrogen receptor (ER)-positive, human epidermal growth factor 2 (HER2)-negative breast cancer. The primary purpose of phase 2 portion of this study is to estimate the efficacy of H3B-6545 in terms of best overall response rate, duration of response (DoR), clinical benefit rate (CBR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) in all participants with ER-positive, HER2-negative breast cancer and in those with and without ER alpha mutation (including a clonal estrogen receptor 1 gene [ESR1] Y537S mutation).
This proposal describes the development of a 'Sensing ET Tube'. This device will replace the standard endotracheal (ET) tube used in anaesthesia and in ventilated intensive care patients and provide key vital signs monitoring utilising optoelectronic sensors. Continuous monitoring of patients' arterial oxygen saturation is essential during surgery, however pulse oximeters often misread or fail altogether as a result of peripheral vasoconstriction, hypotension or hypovolaemia. The Sensing ET Tube will allow continuous measurement of oxygen saturation and other parameters, such as pulse rate, from a single internal site, and will reduce the number of surface sensors placed on the skin and the number of electrical connections to the patient. The applicants have already developed similar sensor technology in the oesophagus and other internal locations. A pilot clinical evaluation of the device will be completed in anaesthetised patients undergoing surgery. The project will lead to further development of a multi-sensor tracheal platform for comprehensive anaesthesia and intensive care monitoring.
This piece of research is a single centre, two-way cross over, prospective study to compare the outcomes and experience of patients completing a paper bladder diary and an electronic version. This project aims to examine whether an electronic bladder diary can improve data quality compared to a paper bladder diary. Participants will attend an introduction appointment within the Urology Department at Royal Hallamshire Hospital. The participant will complete the bladder diaries at home and will then complete a questionnaire at the Royal Hallamshire Hospital. Patients who are being sent an appointment for urodynamics (standard or video) will be also sent a recruitment letter and participant information sheet (PIS), to inform them of the study. One week later a member of the study team will phone the patient, to see if they are interested in participating in the study and assess the eligibility criteria. If that patient is interested and they fulfil the inclusion/exclusion criteria they will be invited to attend an introduction appointment. This will be conducted 1-2 weeks prior to the urodynamic test, at which point study details will be discussed and written informed consent will be taken. The participant will be taught how to use the digital and paper versions of the bladder diaries Participants will be asked to complete the electronic diary for three days and the paper diary for three days. Half of the participants will complete the digital diary first, the other half will complete the paper diary first, and this will be done by alternating consecutively. Patients will be asked to record the time and volume of voids, any incontinence or urgency episodes and sleep-wake times. On the day of their urodynamics appointment, patients should return with their electronic and paper diaries
Fatigue is common and disabling for most patients with inflammatory rheumatic disease. Therapies designed to improve physical activity and 'talking' treatments, which positively help patients change the way they think and behave, are both helpful in reducing the burden of the fatigue. However, few patients have access to these treatments in most health services. This situation results from the absence of standardised programmes and limited availability of relevant therapists. The investigators aim to enhance access to fatigue alleviating physical activity and talking therapies by testing innovative,standardised and cost-effective approaches to treatment delivery. The investigators will also use this opportunity to understand how to select the best treatment for a patient based on their individual profile and to better understand how these treatments actually work. This in turn may lead to more refined and effective therapies in the future.
There is little information on the dietary intake, absorption, metabolism and bioavailability (degree to which a substance becomes available to the target tissues upon administration) of polyphenols (natural substances present in a variety of foods) in human participants. This study assessed the bioavailability in healthy participants of polyphenols from 2 supplements containing green tea and green coffee extracts. Eleven participants were recruited and their habitual diet was assessed to estimate polyphenol intake. After completing a 24-hour urine collection, participants were given six green tea extract and three green coffee extract tablets, which they took daily for a period of 8 weeks. No tablets were taken during the last 4 weeks of the study. Further 24-hour urines were collected at 2, 4, 8 and 12 weeks. Participants were required to attend HNR (medical laboratory) the day after each 24hour urine collection. At these visits, they were asked to bring along their urine collections, completed documents (urine collection sheet, checklist for tablet intake/side effects) and any remaining supplements, which were used to assess tablet compliance. The investigators identified and quantified the amount of polyphenols in the supplement tablets as well as the amount of polyphenols and their metabolites in urine. The investigators then evaluated polyphenol bioavailability from the relationship between their dietary intake and urinary output. Evidence from this research could inform future intervention studies by providing data on the bioavailability of green tea and coffee polyphenols, and on the individual differences related to phenolic intake.
Acute appendicitis is the most common surgical emergency in childhood. Despite access to current diagnostic modalities, diagnosis may be challenging since the child may have difficulty in articulating symptoms. Additionally there is a high frequency of atypical presentation and rapid progression. Delayed diagnosis in children is reported as being up to 60%. Delayed diagnosis >48hr increases the perforation rate from 21% to 71%. Around 20% of children presenting with appendicitis have perforated by the time they come to surgery. Appendix perforation is associated with a prolonged hospital stay and increased cost. Once perforated, major complication rates increase from 1.2% to 6.4%, median bed stay increases from 2 to 6 days and hospitalisation costs are estimated at US $33,348. Conversely, a false positive diagnosis leads to unnecessary surgery in 12%. It has been suggested that only 35% of surgical referrals with possible appendicitis actually need surgery thus impacting on resource use. A reliable test, especially if painless, would be very useful. If positive the child could undergo early appendicectomy in expectation of a reduction in the perforation rate (and, therefore, reduction in hospital stay). If negative the child could be discharged home safely. No adequate biomarker has been identified. Technology already exists to detect changes in Volatile Organic Compounds (VOC) in gases. VOC analysis is already used commercially to identify disease processes in animals and crops. Although VOC has been previously used to detect human diseases, it has never been used to look for changes in the composition of breath in appendicitis. The investigators hypothesise that the composition of VOC's in children with appendicitis will differ from those without. The investigators anticipate these differences will be of diagnostic and prognostic value in clinical practice. The feasibility of collecting breath samples from children with possible appendicitis to allow VOC testing has not been examined.

The present study will examine the role of circulating RNA complexed with autoantibodies and immune complexes and its role in activation of inflammatory pathways in patients with primary Sjogren's syndrome. The study will be conducted in a subset of Sjogren's patients who have elevated levels of autoantibodies and a pattern of elevated interferon-stimulated gene expression in blood cells. A number of biochemical and clinical parameters will be analyzed to determine the potential therapeutic utility of nuclease therapy in Sjogren's syndrome.
This is a prospective single arm study enrolling patients who are scheduled for creation of a new Brachiocephalic or Radiocephalic AV fistula. Up to 80 patients will be enrolled, 50 with upper arm AV fistula and 30 with forearm AV fistula. All patients will be implanted with the VasQ device, a subcutaneous arteriovenous conduit support for vascular access. The follow up period in this study will be for a duration of 12 months, with follow up visits scheduled at 1, 3, 6, 9, and 12 months.
