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 investigators intend to undertake a study to investigate the effect of radiotherapy on deep inferior epigastric perforator flap reconstructions (DIEP). Adjuvant post-mastectomy radiotherapy (PMRT) is offered to women at high risk of chest wall recurrence. The perceived detrimental effect of radiotherapy on an immediate breast reconstruction and the "one-off" nature of autologous reconstruction leads some surgeons to recommend delayed reconstruction after mastectomy or to use a temporising implant with a view to planned exchange to autologous reconstruction after radiotherapy. However, there remains significant uncertainty in the literature about the impact of radiotherapy on autologous reconstructions. This study is a mixed methology study using patient reported outcome measures (PROMS), applanation tonometry (measure of breast compressibility), semi-structured interviews and 3 dimensional photography analysis to compare the aesthetic and impact on quality of life on the following groups of patients: Patient groups: 1. Unilateral skin sparing mastectomy (SSM) with immediate DIEP flap reconstruction and PMRT (cases) 2. Unilateral SSM with immediate DIEP flap reconstruction and no PMRT (controls) 3. Unilateral simple mastectomy, PMRT, and subsequent delayed DIEP flap reconstruction (controls) 4. Unilateral SSM with temporizing implant, PMRT and subsequent conversion to DIEP (controls)
Recent data have suggested that monocyte oxidative burst defect is associated with the development of infection in patients with severe alcoholic hepatitis. One report found reduced 28 day mortality in patients treated with N-acetylcysteine combined with prednisolone when compared to prednisolone alone. The current study seeks to reveal whether the mechanism by which NAC reduces susceptibility to infection is through improvement of phagocyte oxidative burst.
This phase III trial studies how well active surveillance help doctors to monitor subjects with low risk germ cell tumors for recurrence after their tumor is removed. When the germ cell tumor has spread outside of the organ in which it developed, it is considered metastatic. Drugs used in chemotherapy, such as bleomycin, carboplatin, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. The trial studies whether carboplatin or cisplatin is the preferred chemotherapy to use in treating metastatic standard risk germ cell tumors.
The rationale for the study is to obtain safety and efficacy data as well as to establish dose parameters for the SpectraCure P18 System with IDOSE®, with verteporfin for injection (VFI) as photosensitizer for the treatment of recurrent prostate cancer.
Worldwide, glaucoma is the most common cause of irreversible blindness. The major risk factor is raised pressure within the eye (intraocular pressure, IOP). IOP is typically measured using Goldman applanation tonometry (GAT). This involves instilling anaesthetic eye drops and using a probe to contact the cornea and obtain a pressure measurement. A major disadvantage of GAT is that only limited numbers of pressure measurements can be obtained, whereas IOP is known to vary throughout the day and in ¾ of people is highest during the night. The result is that clinicians have poor understanding of patient's 24 hour IOPs and the effect that this might have on their glaucoma. This is a serious limitation as the treatment of glaucoma depends on lowering IOP. Recently a new device has become available, designed specifically for home IOP monitoring. The iCare HOME tonometer is a CE marked commercial device (http://www.icaretonometer.com/products/icare-home-tonometer/) that can be used to gain insight into 24-hour IOP fluctuations. We wish to determine the feasibility of home IOP monitoring using this device. The iCare HOME tonometer depends on the patient performing self-tonometry. Testing one's own IOP may be technically difficult and it is likely that large numbers of patients will struggle with this.
Sampling of accessed root canals with endodontic paper points during treatment and immediately pre-obturation of endodontic root canals was carried out.
This is a feasibility study to test a new trial design for an important drug in Systemic Lupus Erythematosus (SLE or "lupus"). SLE is an autoimmune disease. The immune system attacks the body's own tissues, any part of the body may be affected, but most commonly lupus causes a rash and arthritis, this affects patients' quality of life. Lupus is usually treated with steroids or drugs that suppress the immune system. Although these help, many patients don't respond well enough and there is also concern for long term side effects. There is a new type of treatment called biologics. These target individual cells or molecules rather than the whole immune system and may be more effective with fewer side-effects. B cells are a part of the immune system that are known to play a role in lupus. There is already a biologic that removes these, called rituximab. In rheumatoid arthritis and vasculitis (similar to lupus), rituximab has been proven to be effective in clinical trials. However, in lupus clinical trials it did not seem to show any benefit. But many doctors and patients found that rituximab is effective, but the trials couldn't show this because of the way the drug's effects were measured. Therefore it is important that we test whether it truly is effective for lupus. In this 6 month clinical study the investigators will look at lupus patients who have skin disease and arthritis as these are very common and randomise them to receive either rituximab or a placebo. Patients will have a careful clinical examination and undergo different methods to measure the effectiveness of the treatment. There are new versions to rituximab called "biosimilars". In this study biosimilar GP2013 will be used. If this trial is successful a larger definitive study will be designed based on its results.
This phase II single centre, double blind, placebo-controlled, randomised trial aims to test the hypothesis that intravenous iron improves exercise performance in Chronic Obstructive Pulmonary Disease (COPD) as measured by constant rate cycle ergometry.
Arrhythmogenic ventricular cardiomyopathy (AVC) is a genetic condition which affects the heart and can lead to heart failure and rhythm problems, of which, sudden cardiac arrest or death is the most tragic and dangerous. Diagnosis and screening of blood-relatives is very difficult as the disease process can be subtle, but sufficient enough, so that the first event is sudden death. The Mayo Clinic AVC Registry is a collaboration between Mayo Clinic, Rochester, USA and Papworth Hospital, Cambridge University Hospitals, Cambridge, UK. The investigators aim to enroll patients with a history of AVC or sudden cardiac death which may be due to AVC, from the US and UK. Family members who are blood-relatives will also be invited, including those who do not have the condition. Data collected include symptoms, ECG, echocardiographic, MRI, Holter, loop recorder, biopsies, exercise stress testing, blood, buccal and saliva samples. Objectives of the study: 1. Discover new genes or altered genes (variants) which cause AVC 2. Identify biomarkers which predict (2a) disease onset, (2b) disease progression, (2c) and the likelihood of arrhythmia (ventricular, supra-ventricular and atrial fibrillation) 3. Correlate genotype with phenotype in confirmed cases of AVC followed longitudinally using clinical, electrocardiographic and imaging data. 4. Characterize desmosomal changes in buccal mucosal cells with genotype and validate with gold-standard endomyocardial biopsies
90 patients with HER2 negative breast cancer will be randomised to receive 18 weeks of chemotherapy treatment, either 6 cycles of 3 weekly Cabazitaxel or 6 cycles of weekly Paclitaxel to determine the difference in progression free survival between the 2 groups. If results at that stage suggest a potential benefit then the trial will be developed further to accrue 70 more patients.
