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.
To evaluate the bioavailability of mycoprotein, compared with a reference animal based protein, in a dose-response manner.
This is a 2-part, phase 3 clinical study evaluating the antiretroviral activity and safety/tolerability of islatravir (ISL), doravirine (DOR), and a fixed dose combination (FDC) of DOR/ISL (also known as MK-8591A) in heavily treatment-experienced (HTE) participants with human immunodeficiency virus type 1 (HIV-1) infection. It is hypothesized that the percentage of participants receiving DOR/ISL to achieve ≥0.5 log10 decrease in HIV-1 ribonucleic acid (RNA) from study baseline (Day 1) to Day 8 is superior to placebo, each given in combination with failing antiretroviral therapy (ART).
Heart failure with preserved ejection fraction (HFpEF) is a complex condition with various causes that is not yet fully understood. Most significantly there is no single method of diagnosing or treating the condition. Recently a novel non-invasive diagnostic criterion to predict the likelihood of HFpEF was proposed called H2FPEF. The main limitation of this study was the use of a single centre population from the Mayo clinic in Rochester, US. Another limitation is that the H2FPEF diagnostic criterion consists of common and often co-existing conditions which could as a result overestimate HFpEF probability. The aim of the investigators is to retrospectively test the H2FPEF criteria on the population at Queen Alexandra Hospital (QAH) in Portsmouth, which is of a lower socio-economic status and greater ethnic diversity. Implications of the proposed project if H2FPEF is proved to be generalizable to the study population is that it can be used within the Trust and rolled out to others. This would allow diagnosis to be made quicker and more cost effectively using echocardiography and without the need for invasive cardiac catheterisation. On the other hand if H2FPEF is found not to be applicable to the population then further research would be required to find the ideal diagnostic tool.

Study Title: The Impact of the pH on cardiac function in the critically ill patient Sponsor: King's College Hospital NHS Foundation Trust Chief Investigator: Dr Sancho Rodríguez-Villar IRAS Number: 227870 Hypothesis: Titration studies in animals with normal cardiac function show that a reduction in blood pH (and presumably that of the intracellular and interstitial compartments) from the normal level of 7.40 to 7.20 is associated with a rise in cardiac output. However, when blood pH is less than 7.20, cardiac output is reduced. Similar studies in humans with or without normal cardiac function have not been done, and yet blood pH at which aggressive treatment is recommended has been set at 7.20 based solely on animal experiments. The investigators hypothesize that a change in blood pH in humans will also affect cardiac function, but the level of blood pH at which this is observed might be similar or different in humans. In addition, the presence or absence of underlying cardiac disease and the type of acid-base abnormality present might modify the response of the heart to changes in blood pH. Primary Objectives: 1. Assess whether there are significant changes in cardiac function associated with changes in blood pH. 2. Relate the changes in cardiac function to the presence or absence of underlying cardiac disease. Study Design: A prospective multicenter observational study in 6 ICU´s (between two Trusts). During a year study period, a minimum of 300 patients will be recruited.
Present treatment of children with stable ankle and foot injuries very often involves a period in plaster cast(s). In the last decade in adult patients this has been superceded in many instances by the use of a removable foot brace/splint. There are many benefits to this approach including progressive rehabilitation, reduced costs in materials and personnel, improved hygiene and adaptability of fit. The use of such a splint has not been investigated in children and this project aims to assess the value of introducing this as a treatment mode through the analysis of outcomes between traditional cast treatment and the newer removable brace/splint treatment. The outcomes will include patients' preferences, clinical results and relative costings.
Clinical Trial of Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) Oxygen in Women having Planned Caesarean Delivery. Cohort study investigating the efficacy of THRIVE pre-oxygenation using pre-determined number of vital capacity breaths and comparing the efficacy to face mask pre-oxygenation. Aimed to recruit ASA 1-2 term pregnant women having elective caesarean section.
Atrial fibrillation (AF) is the most common sustained arrhythmia, with increasing prevalence associated with an ageing population. Management is challenging, and invasive catheter ablation procedures are increasingly used in those with symptoms refractory to drug therapy. Unfortunately, success rates from this procedure can be limited. This is partly due to limitations in understanding of the mechanisms involved in arrhythmia propagation. There is much interest in the role of structural changes within the muscle of the left atrium resulting in scaring (known as fibrosis). This has been identified on MRI studies and invasive electroanatomical mapping using voltage amplitude of recorded signals as a surrogate measure of tissue properties. This however is affected by the technology used, as it does not routinely incorporate the effect of heart rate on conduction properties. Furthermore, although this aims to identify regions of structural changes, it does not identify more dynamic patterns of conduction seen during AF. This study aims to use a high density mapping catheter (Abbott Advisa HD grid (SE)), which employs a novel algorithm to minimise the effect of wavefront direction on the size of electrical signals. Electroanatomical mapping of the left atrium in patients with atrial fibrillation will be conducted whilst pacing at long and short cycle lengths to assess the effect of pacing rate on conduction properties, assessed using signal morphology and conduction velocity. The same procedure will also be carried out in 5 control patients to allow comparison with normal atria. Two subgroups will also analysed. In the first the aim is to compare the use of the HD grid catheter to a bipolar ablation catheter in carrying out electroanatomical mapping. In the second, to correlate electrical signals obtained with propagation patterns identified using the AcQMap non-contact mapping system and atrial properties identified on cardiac MRI.

The primary PK objectives were: - Part 1: To characterize systemic PK of voriconazole and N-oxide voriconazole after single doses of ZP-059 in healthy subjects - Part 2: To characterize systemic PK of voriconazole and N-oxide voriconazole after multiple doses of ZP-059 in subjects with mild stable asthma - Part 3: To characterize systemic PK of voriconazole and N-oxide voriconazole after single doses of ZP-059 and single doses of oral voriconazole in subjects with mild to moderate stable asthma.
Childhood arthritis is a diagnosis made by clinicians based upon their clinical examination, during which patients are assessed for signs of swelling, warmth and restricted movement of the joints using the sensation of touch. Clinicians use investigations such as blood tests and scans which may be costly, associated with waiting times, can cause the patient stress or anxiety. Patients with childhood arthritis can often present with flares of their condition even when on medical treatment, which may require further investigations to determine the nature of the problem. Studies in adult Rheumatology have demonstrated that a thermal imaging camera (which detects heat given off by the body) can be useful in assessing for signs of inflammation in arthritis. The use of this camera could provide an alternative to the tests described; it does not require any contact with the patient, is quick and easy to use, and does not emit any radiation. The investigators hope that this pilot study will demonstrate that thermal imaging can be used to complement the standardised assessments of joint inflammation as done routinely in clinic and may lead to further work comparing thermal imaging with other tests such as MRI scanning and ultra-sound. The investigators will recruit 20-50 children with arthritis affecting either knee or ankle joints. The investigators will use a highly sensitive thermal imaging camera to take pictures and short video recordings of each ankle and knee joint, recording skin temperature and colour. The investigators will compare this with the clinicians' assessment of whether the knee and ankle joints are inflamed or not. The investigators are interested in finding out whether the information recorded using the camera mirrors the assessment made by the clinician.
