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 Covid-19 viral pandemic has caused significant global losses and disruption to all aspects of society. One of the major difficulties in controlling the spread of this coronavirus has been the delayed and mild (or lack of) presentation of symptoms in infected individuals, and the insufficient Covid-19 testing capacity in the UK. This warrants the development of alternative diagnostic tools that reliably assess Covid-19 infection in the early stages of infection, while also being low- cost, low-burden, and easily administered to a wide proportion of the population. This study aims to validate machine learning models as a diagnostic tool that predicts infection with SARS-CoV-2 based on app-reported symptoms and phenotypic data, against the 'gold-standard' swab PCR-test. This study will take place within the Covid Symptom Study app, the free symptom tracking mobile application launched in March 2020.
People with incurable cancer often have complex individual needs, however there are several common themes encountered when considering this group. As cancer progresses there are series of interactions between the tumour and the patient, producing both local and systemic effects. This altered state of illness can have multiple ill effects including weight loss, fatigue, increased symptom burden and reduction in physical function which all contribute to a reduced quality of life. These areas are often studied in isolation, giving an incomplete picture. A detailed, holistic characterisation of this group of people does not exist. A robust characterisation of people with incurable cancer will allow identification and prioritisation of future research and has the potential to inform new therapeutics and provide justification for treatments. This study aims to collect information about symptoms and quality of life, weight loss and body composition, physical activity and the body's immune response to cancer. Participants with incurable cancer will be recruited to the study from oncology and palliative medicine services in the UK. Participants will answer questionnaires about quality of life and symptoms, have bloods taken for inflammatory marker and cytokine analysis and have their body composition measured by a variety of methods.
A novel Coronavirus (COVID-19) infection leading to pneumonia and severe acute respiratory failure [acute respiratory distress syndrome (ARDS)] and death is a global threat. On 11/03/2020, WHO declared the Covid-19 outbreak a global pandemic. As of 18th of March, there are 202,309 confirmed cases with 8,013 deaths. Patients with severe illness may develop dyspnoea and hypoxemia within 1week after onset, which may quickly progress to ARDS or end-organ failure 1. Based on Chinese data abnormal coagulation parameters (Prolonged Prothrombin time [PT] and raised D dimer) are reported to predict a poor prognosis and may therefore be important therapeutic targets. The number of patients with infected with COVID- 19 in UK is rapidly rising as with many other European countries. Eventually >50% of people will have become infected and COVID-19 will remain a public health threat in the long term. It is therefore very important to understand every aspect of this disease, including the associated coagulopathy leading bleeding, blood clots (thrombosis) and death. Emerging data from Europe and some centres in UK, indicates that venous thromboembolism (VTE), mainly pulmonary embolism (PE), is major problem in COVID patients. In this retrospective-prospective: multicentre study, investigators will document the patient characteristics, presenting haematological parameters and associated comorbidities and their association with bleeding, thrombosis and mortality in patients admitted for hospital treatment. Determining the predictive value of patient characteristics and presenting laboratory measurements for clinical outcomes in these patients will allow us to optimise management of these patients in the future. Furthermore, by comparing these data with data from patients without Covid-19, investigators will be able to modify existing protocols and tailor them to the management of COVID -19.
This study uses a Doppler ultrasound technique being developed at the University of Leicester called 'Brain Tissue Velocimetry" (Brain TV), to investigate brain tissue motion over the cardiac cycle.
The primary objective of this project is to understand the reasons why patients agree / disagree to take part in ophthalmology research. This will be done by asking participants to complete a Research Questionnaire.
Richmond Research Institute (RRI) is applying existing and new COVID-19 PCR and antibody tests to help develop methodologies which provide fast and accurate results. Infection with coronavirus (SARS-CoV-2) is currently a worldwide pandemic and reliable testing for COVID-19 is crucial to understand who is infected and therefore a risk to others by spreading the infection. RRI are currently carrying out the following tests: A. Using a membrane-based immunoassay to detect IgG and IgM antibodies to SARS-CoV-2 in whole blood, serum or plasma specimens helps to assess whether an individual has previously had the virus and is potentially immune B. Polymerase Chain Reaction (PCR) testing using an established method to check for active SARS-CoV-2 infections. C. Quantification of anti-SARS-CoV-2 IgG and IgM antibodies in whole blood samples. The above tests are being used by RRI to follow infections (PCR) and immunity (IgG) in their workforce, as well as their families (including children) and visitors to their site. Collecting this data allows the gathering of epidemiological data on SARS-CoV-2 including incidence, prevalence, information on asymptomatic carriers and efficacy of vaccination. Furthermore, identifying individuals that are infected with SARS-CoV-2 has great potential to improve health outcomes by allowing infected individuals to seek the correct medical treatment as well as self-isolate and reduce transmission.
MIRRORS "Minimally Invasive Robotic Surgery, Role in Optimal Debulking Ovarian Cancer, Recovery & Survival" is a new United Kingdom based prospective feasibility study the purpose of which is to establish the feasibility of launching a British multicentre randomised control trial of Robotic interval debulking surgery for ovarian cancer (including cancer of the fallopian tube & peritoneum) in the future. This initial feasibility study will focus on the ability to recruit patients, acceptability, quality of life, the rate at which it is possible to remove all visible tumour and the rate of conversion to open surgery. Ultimately the investigators would like to determine whether, in selected patients, robotic surgery offers improved quality of life and recovery with equivalent overall and progression free survival. Robotic surgery is unlikely to be suitable in all cases of ovarian cancer, particularly those with large pelvic masses or extensive disease around the upper part of the abdomen, however, it has the potential to provide significant recovery and quality of life benefits to a selected group of patients. MIRRORS - ICG "Peritoneal angiography / perfusion assessment using Indocyanine green (ICG) in patients with advanced ovarian cancers" is a ancillary study within MIRRORS. Using ICG dye, the investigators aim to observe whether there are any changes in the blood vessel pattern associated with the tumour deposits the investigators remove that makes them distinctive. The ICG will not be used to guide where biopsies are taken or tissue is removed. Participation in this ancillary research is not required for participation in the trial.
The investigators intend to investigate the carriage of pneumococci and other respiratory microbes since the introduction of pneumococcal conjugate vaccines (Prevenar 7 and Prevenar 13). The principal aim is to gain a collection of samples that can be used to help investigate any changes that might occur in the epidemiology of microbes that are carried in the upper respiratory tract and which may cause respiratory disease, sepsis or meningitis after the introduction of Prevenar. Nasopharyngeal and nasal swabs will be taken from up to 2,000 children aged 4 years and under in each year of the study. Swabs will be processed using traditional microbiology and molecular diagnostic techniques and isolated microbes such as S. pneumoniae further characterised using molecular methods. The investigators will also ask parents to complete a short questionnaire requesting: basic demographic data; vaccine history; recent illness; overseas travel and antibiotic usage. The study will contribute to the success of the introduction of pneumococcal conjugate vaccines and will play a central role in maintaining confidence. The study will also help provide information for future vaccine policy as further vaccines are developed against microbes which cause respiratory disease, sepsis and meningitis.
In the United Kingdom, there are currently 138,000 confirmed patients with coronavirus, causing 18,738 deaths. Whilst the disease may be mild in the majority of patients, a significant proportion of patients require intensive care therapy and a ventilator due to lung injury. In addition to lung injury/failure (acute respiratory distress syndrome (ARDS)), around 50% of patients admitted to intensive care develop acute kidney injury (AKI) (requiring advanced support via haemofiltration) and multi-organ failure. It is unclear why patients suffering from COVID-19 develop such severe lung injury (requiring life support or ventilation) or indeed why patients develop other organ dysfunction such as kidney injury. The investigators hypothesis that this may due to an over-reaction of the immune system particularly in the lungs. This then results in the release of various mediators and biological messengers which can be pushed into the blood bloodstream (exacerbated by positive pressure generated by the ventilator). These mediators then travel, via the blood, to other organs such as the kidney where they cause inflammation and injury of cells, resulting in organ failure. The investigators would like to apply their well-established laboratory methods to further the scientific community's knowledge of this severe and deadly viral condition and we hope that this would lead to the development of medication that would treat this deadly virus.
