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.
This proposed randomized, double blinded 12 week crossover human feeding study aims to investigate the effects of consuming a composite drink of inulin and arabinoxylan on satiety by measuring appetite biomarkers such as subjective satiety, energy/food intake and changes in the human gut microbiota in healthy weight males (22 to 24.9kg/m2)
Total knee replacement (TKR) is an established treatment for knee osteoarthritis and leads to a satisfactory outcome in over 75% of patients. The pain and function after TKR can be dependent on the accuracy of initial implantation, as deviation of more than 3 degrees from the normal alignment of the limb can lead to abnormal stresses on the implant and accelerated failure. Patient specific cutting blocks may result in a more individualised implant placement, improved pain and function following surgery, and a long-lasting implant. This trial is designed to investigate if there is any benefit to bespoke instrumentation in terms of pain and function to the patient, and an economic benefit to the NHS.
Human Papilloma Virus (HPV) has been shown to be a cause of Head & Neck Squamous Cell Carcinoma (HNSCC) and the majority of current studies focus on what is happening in patients with a HPV HNSCC. But there is limited investigation into HPV infection in the oropharynx of patients who do not have HNSCC. The current incidence of oral HPV infection is not known in the general population locally and there is also limited information on what particular localities within the mouth that patients' harbour HPV infection what strains are present and if there are any differences in viral load. Therefore the aim of this project is to investigate within patients that undergo tonsillectomies the rate of HPV infection in tonsils to determine the amount of HPV present within the community.
There are currently many surgical options for patients with glaucoma and ocular hypertension (OHT), including the Hydrus Microstent implant, HiFU (High intensity Focused ultrasound), STAR flo, Kahook Dual Blade, Diode laser, trabeculectomy and the Baerveldt implant, but little is known about how these different surgical techniques used to treat glaucoma affect the flow of fluid through and out of the eye (aqueous dynamics).
The purpose of this study is to determine weather using warmed (body temperature) 0.75% Ropivicaine to convert labour epidural analgesia to surgical anaesthesia, reduces the onset time of surgical block, compared to standard room temperature
SPECTA is a quality assured platform for collecting clinicopathologically annotated biological material, imaging data, operative images, environmental assessment, questionnaires as well as patient-reported outcomes from cancer patients to support biospecimen-based translational research and clinical cancer research, including biomarker discovery to improve the understanding of tumor biology and cancer patients care.
The purpose of the study is to measure the drug levels in the blood of HIV-infected individuals taking anti- HIV medication efavirenz 400 mg once daily in the presence of anti-TB medication rifampicin and isoniazid. The study is being run in two-stages - London (Stage 1) and Kampala (Stage 2). In London (Stage 1): HIV-1 infected patients (without tuberculosis infection) on established treatment with a combination based on 600 mg efavirenz dose will be recruited. In Kampala (Stage 2): Patients with both HIV-1 and tuberculosis infection being treated with 600 mg efavirenz combination for HIV AND undergoing TB treatment with a dual therapy regimen contaning rifampicin and isoniazid will be recruited. Efavirenz-containing regimens are recommended as first-line therapy for HIV-TB co-infected patients. It has been shown there is a lack of a significant difference between efavirenz 400 mg and efavirenz 600 mg, indicating that 400 mg efavirenz is non-inferior to the standard dose. The advantages of antiretroviral dose reductions may translate into greater benefits for more individuals infected by HIV globally, since they may allow access programs to reach higher numbers of infected patients and compensate for the finite global manufacturing capacity and increasing demand. For efavirenz, significant price reductions have been achieved through elimination of trade, logistics and manufacturing capacity barriers, and further price reductions could be achieved with a significant reduction in the cost of pharmaceutical ingredients. However, no data on the PK and effectiveness of efavirenz 400 mg once daily during TB treatment has been produced. Given that many patients on Efavirenz- based ART will need to be treated for TB during their lifetime and rifampicin is one of the most commonly used treatment for tuberculosis, it is important to study the reduced dose under carefully monitored conditions prior to roll out of a lower dose standard treatment. Therefore, we aim to investigate the PK of efavirenz 400 mg once daily in HIV-infected individuals in the presence of rifampicin and isoniazid in London, UK and in HIV/TB-co-infected individuals on dual anti-TB treatment in Kampala, Uganda
The Computerized Registry of Patients with Venous Thromboembolism (RIETE) is a multidisciplinary Project initiated in march 2001 and consisting in obtaining an extensive data registry of consecutive patients with venous thromboembolism. The main objective is to provide information on the Internet to help physicians to improve their knowledge on the natural history of thromboembolic disease, particularly in those subgroups of patients who are usually not recruited in randomized clinical trials (pregnant women, elderly patients, disseminated cancer, severe renal insufficiency, patients with contraindications to anticoagulation therapy, extreme body weight, etc), with the purpose of decreasing mortality, frequency of thromboembolic recurrences as well as bleeding complications and arterial events. As an additional objective RIETE is also aimed to create predictive scores that help physicians to better identify patients with high risk of presenting some of these complications. The primary parameters recorded by the registry comprise details of each patient's clinical status, including any coexisting or underlying conditions, and the type, dose, duration and outcome (during the first 3 months of therapy) of antithrombotic treatment. Study endpoints are clinically recognized (and objectively confirmed) recurrences of VTE, major and minor bleeding complications, and death.
INTRODUCTION Carpal tunnel syndrome (CTS) is a common condition that results in impaired hand function. In cases of CTS the "pinch grip" force between the thumb and index finger becomes unnecessarily high to prevent objects from slipping when they are picked up. HYPOTHESES The proposed study will investigate the following hypotheses regarding CTS. As an object is picked up, the investigators suspect there will be several points at which grip force will be different between patients with different severities of CTS, i.e. grip may deteriorate as CTS gets worse. The investigators also suspect grip force will be affected depending on the weight of the object, i.e. patients with CTS may struggle with objects of a certain weight. Patients with CTS sweat less, and this may affect their grip. The investigators suspect that pinch grip in CTS patients is disproportionately altered by the frictional properties of the object and by the moistness of the skin. The investigators suspect patients with CTS will be less able to adapt to sudden changes in an object's weight. The investigators wish to examine how the above are affected after surgical treatment of CTS. METHODS The investigators will include patients with symptomatic, idiopathic CTS, aged between 18 and 80 years. The investigators' centre will recruit CTS patients who will attend their National Health Service (NHS) outpatient appointment followed by nerve conduction studies. An equal number of healthy participants will be recruited for comparison purposes. At the aforementioned appointment, patients will undertake a pinch grip force test using a device that will test the above points. Patients will have normal care under their surgeon, which may include an operation for treatment of CTS. Therefore some patients will be invited back to have grip tests again after their operation. No aspect of the study will prevent a patient from receiving their normal National Health Service (NHS) care.
